MC74AC08 and MC74ACT08 are quad 2-input AND logic gates with output drive capability of 24 mA. MC74ACT08 has TTL compatible inputs.

The MC74AC/ACT05 is a device that is pin-compatible with the LS05. The device inputs are compatible with standard CMOS outputs and, with pull-up resistors, they are compatible with TTL outputs. The outputs can source/sink 24 mA, and the ′ACT05 has TTL-compatible inputs.

MC74AC02/MC74ACT02 is a digital logic device of the MC74 series, belonging to a quad 2-input NOR gate, with an output current of up to 24mA, and can be compatible with TTL circuits

This document describes the characteristics of MC74AC00 and MC74ACT00, two quad 2-input NAND gates. They have TTL compatible inputs and can output a current of 24mA. The maximum ratings include VCC from -0.5V to +7V, input/output voltage from -0.5V to VCC+0.5V, maximum input current of ±20mA, and maximum output sink/source current of ±50mA.

The MC10E/100E196 is a programmable delay chip (PDC) designed primarily for very accurate differential ECL input edge placement applications. The delay section consists of a chain of gates and a linear ramp delay adjust organized as shown in the logic symbol. The first two delay elements feature gates that have been modified to have delays 1.25 and 1.5 times the basic gate delay of approximately 80 ps. These two elements provide the E196 with a digitally-selectable resolution of approximately 20 ps. The required device delay is selected by the seven address inputs D[0:6], which are latched on chip by a high signal on the latch enable (LEN) control. The FTUNE input takes an analog voltage and applies it to an internal linear ramp for reducing the 20 ps resolution still further. The FTUNE input is what differentiates the E196 from the E195. An eighth latched input, D7, is provided for cascading multiple PDC’s for increased programmable range. The cascade logic allows full control of multiple PDC’s, at the expense of only a single added line to the data bus for each additional PDC, without the need for any external gating.

The MC10E/100E195 is a programmable delay chip designed primarily for clock de-skewing and timing adjustment. It provides variable delay of a differential ECL input transition. The chip offers high resolution and frequency, allowing for very accurate system clock timing selectable entirely from a digital input.

The file is a product datasheet of MC10E195/D from Motorola company. MC10E195/D is a programmable delay chip (PDC) designed primarily for clock de-skewing and timing adjustment. It provides variable delay of a differential ECL input transition. The delay section consists of a chain of gates organized as shown in the logic symbol. The first two delay elements feature gates that have been modified to have delays 1.25 and 1.5 times the basic gate delay of approximately 80 ps. These two elements provide the E195 with a digitally-selectable resolution of approximately 20 ps. The required device delay is selected by the seven address inputs D[0:6], which are latched on chip by a high signal on the latch enable (LEN) control. Because the delay programmability of the E195 is achieved by purely differential ECL gate delays the device will operate at frequencies of >1.0 GHz while maintaining over 600 mV of output swing. The E195 thus offers very fine resolution, at very high frequencies, that is selectable entirely from a digital input allowing for very accurate system clock timing. An eighth latched input, D7, is provided for cascading multiple PDC’s for increased programmable range. The cascade logic allows full control of multiple PDC’s, at the expense of only a single added line to the data bus for each additional PDC, without the need for any external gating.

The MC10E/100E193 is an error detection and correction (EDAC) circuit. Modified Hamming parity codes are generated on an 8-bit word according to the pattern shown in the logic symbol. The P5 output gives the parity of the whole word. The word parity is also provided at the PGEN pin, after Odd/Even parity control and gating with the BPAR input. This output also feeds to a 1-bit shiftable register, for use as part of a scan ring. Used in conjunction with 12-bit parity generators such as the E160, a SECDED (single error correction, double error detection) error system can be designed for a multiple of an 8-bit word.

The MC10E/100E175 is a 9-bit latch. It also features a tenth latched output, ODDPAR, which is formed as the odd parity of the nine data inputs (ODDPAR is HIGH if an odd number of the inputs are HIGH). The E175 can also be used to generate byte parity by using D8 as the parity-type select (L = even parity, H = odd parity), and using ODDPAR as the byte parity output. The LEN pin latches the data when asserted with a logical high and makes the latch transparent when placed at a logic low level.
