The MM74C14 Hex Schmitt Trigger is a monolithic complementary MOS (CMOS) integrated circuit constructed with N- and P-channel enhancement transistors. It has wide supply voltage range, high noise immunity, low power and TTL compatibility.

MM74C221 is a dual monostable multivibrator produced by Fairchild Semiconductor

MM74C86 is a quad 2-input exclusive-OR gate produced by Fairchild Semiconductor Corporation. It uses complementary metal oxide semiconductor (CMOS) transistors to achieve a wide power supply operating range, low power consumption, and high noise margin, and provides basic functions for implementing digital integrated circuit systems.

The MM74C906 and MM74C907 buffers employ monolithic CMOS technology in achieving open drain outputs. The MM74C906 consists of six inverters driving six N-channel devices; and the MM74C907 consists of six inverters driving six P-channel devices. The open drain feature of these buffers makes level shifting or wire AND and wire OR functions by just the addition of pull-up or pull-down resistors. All inputs are protected from static discharge by diode clamps to VCC and to ground.

The MM74C911 display controller is an interface element with memory that drives a 4-digit, 8-segment LED display. The MM74C911 allows individual control of any segment in the 4-digit display. The number of segments per digit can be expanded without any external components. For example, two MM74C911's can be cascaded to drive a 16-seg- ment alpha-numeric display. The display controllers receive data information through 8 data lines a, b…DP, and digit information through 2 address inputs K1 and K2. The input data is written into the register selected by the address information when CHIP ENABLE, CE, and WRITE ENABLE, WE, are LOW and is latched when either CE or WE return HIGH. Data hold time is not required. A self-contained internal oscillator sequentially presents the stored data to high drive (100 mA typ.) 3-STATE output drivers which directly drive the LED display. The drivers are active when the control pin labeled SEGMENT OUTPUT ENABLE, SOE, is LOW and go into 3-STATE when SOE is HIGH. This feature allows for duty cycle brightness control, or for disabling the output drive for power conservation. The digit outputs directly drive the base of the digit transis- tor when the control pin labeled DIGIT INPUT OUTPUT, DIO, is LOW. When DIO is HIGH, the digit outputs are disabled and the digit inputs are available for external control of the digit segment decoders.

The document describes the features and characteristics of the MM74C922 and MM74C923 CMOS key encoders. They provide all the necessary logic to fully encode an array of SPST switches. These encoders also have on-chip pull-up devices which permit switches with up to 50 kΩ on resistance to be used. No diodes in the switch array are needed to eliminate ghost switches. The internal debounce circuit needs only a single external capacitor and can be defeated by omitting the capacitor. A Data Available output goes to a high level when a valid keyboard entry has been made. The Data Available output returns to a low level when the entered key is released, even if another key is depressed. The Data Available will return high to indicate acceptance of the new key after a normal debounce period; this two-key roll-over is provided between any two switches. An internal register remembers the last key pressed even after the key is released. The 3-STATE outputs provide for easy expansion and bus operation and are LPTTL compatible.

The MM74C925, MM74C926, MM74C927, and MM74C928 are 4-digit counters with multiplexed 7-segment output drivers. They are CMOS counters that have an internal output latch, NPN output sourcing drivers for a 7-segment display, and internal multiplexing circuitry. The counters advance on the negative edge of the clock and can be reset to zero using the reset input. The latch enable input allows for latching the numbers in the counters into the internal output latches. The display select input determines which number is displayed. The MM74C925 is a 4-decade counter with latch enable, clock, and reset inputs. The MM74C926 is similar to the MM74C925, but it also has a display select input and a carry-out output for cascading counters. The carry-out signal goes high at 6000 and goes back low at 0000. The MM74C927 is similar to the MM74C926, but the second most significant digit divides by 6 instead of 10.

The LMV321/358/324 is a low cost, voltage feedback amplifier that consumes only 80µA of supply current per amplifier. The LMV3XX family operates from 2.7V (±1.35V) to 5.5V (±2.75V) supplies. The common mode voltage range extends below the negative rail and the output provides from -0.25V to +2.69V. The series is designed in a CMOS process and provides 1.2MHz of bandwidth and 1.5V/µs of slew rate at a low supply voltage of 2.7V. The combination of low power, rail-to-rail performance, low cost and high performance make the LMV3XX family ideal for a wide range of applications.
