The MC100ELT23 is a dual differential PECL to TTL translator. It has 3.5ns typical propagation delay, differential PECL inputs, small outline SOIC package, 24mA TTL outputs and flow through pinouts.

This datasheet introduces the working principle of MC74AC259/74ACT259 8-bit addressable latch, which is a high-speed latch for general purpose storage applications in digital systems

The MC74AC258/74ACT258 is a quad 2-input multiplexer with 3-state outputs. It selects four bits of data from two sources under control of a common Select input. The four outputs present the selected data in the complement (inverted) form. The outputs may be switched to a high impedance state with a HIGH on the common Output Enable (OE) input, allowing the outputs to interface directly with bus-oriented systems.

MC74AC257/74ACT257 is a quad 2-input multiplexer with 3-state outputs. It selects four bits of data from two sources under control of a Common Data Select (S) input.

The datasheet details the functions and features of the MC74AC256/74ACT256 dual addressable latch, including operating modes, pin definitions, logic symbols, and application circuits.

The MC74AC253/74ACT253 is a dual 4-input multiplexer with 3-state outputs. It can select two bits of data from four sources using common select inputs. The outputs may be individually switched to a high impedance state with a HIGH on the respective Output Enable (OE) inputs, allowing the outputs to interface directly with bus oriented systems. Multifunctional Capability, Noninverting 3-State Outputs, Outputs Source/Sink 24 mA, ′ACT253 Has TTL Compatible Inputs.

The MC74AC251/74ACT251 is a high-speed 8-input digital multiplexer. It provides, in one package, the ability to select one bit of data from up to eight sources. It can be used as a universal function generator to generate any logic function of four variables. Both true and complementary outputs are provided.

The MC74AC244/74ACT244 is an octal buffer and line driver designed to be employed as a memory address driver, clock driver and bus oriented transmitter/receiver which provides improved PC board density.

The MC74AC241/74ACT241 is an octal buffer and line driver designed to be employed as a memory address driver, clock driver and bus oriented transmitter or receiver which provides improved PC board density.

MC74AC20/MC74ACT20 is a dual 4-input NAND gate. The two models differ in that MC74ACT20 has TTL compatible inputs. The device operates over a supply voltage range of -0.5~+7V, with input current of -20mA and output current of 24mA.

MC74AC194/74ACT194 is a high-speed 4-bit bidirectional universal shift register. As a high-speed multifunctional, sequential building block, it is useful in a wide variety of applications. It may be used in serial-serial, shift left, shift right, serial-parallel, parallel-serial, and parallel-parallel data register transfers. The ′AC/ACT194 is similar in operation to the ′AS195 universal shift register, with added features of shift left without external connections and hold (do nothing) modes of operation.

The MC74AC190 is a reversible BCD (8421) decade counter which features synchronous counting and asynchronous presetting.

The MC74AC/ACT175 is a high-speed quad D flip-flop. The device is useful for general flip-flop requirements where clock and clear inputs are common. The information on the D inputs is transferred to storage during the LOW-to-HIGH clock transition. The device has a Master Reset to simultaneously clear all flip-flops, when MR is low. The MC74AC/ACT175 consists of four edge-triggered D flip-flops with individual D inputs and Q and Q outputs. The Clock (CP) and Master Reset (MR) are common to all flip-flops. Each D input’s state is transferred to the corresponding flip-flop’s output following the LOW-to-HIGH Clock (CP) transition. A LOW input to the Master Reset (MR) will force all Q outputs LOW and Q outputs HIGH independent of Clock or Data inputs. The MC74AC/ACT175 is useful for applications where the Clock and Master Reset are common to all storage elements.
