MM74HCT74MTCX

The MM74HCT74MTCX is a dual D-type flip-flop integrated circuit manufactured by On Semiconductor. It utilizes advanced silicon-gate CMOS technology, providing high noise immunity and low power consumption while maintaining speeds comparable to LS-TTL parts. This device features independent data, preset, clear, and clock inputs, along with Q and Q outputs. The logic level at the data input is transferred to the output during the positive-going transition of the clock pulse. Preset and clear functions are independent of the clock and are activated by a low level at the respective input.

Key electrical specifications include a nominal supply voltage of 5V, a clock frequency of 27 MHz, and a maximum propagation delay of 35ns at 5V and 50pF. The operating temperature range is -40°C to 85°C. The flip-flop has a fanout capability of 10 LS-TTL loads and a low quiescent current of 2 µA.

This component is housed in a 14-TSSOP package with surface mount mounting type. It is designed to interface between TTL and NMOS components and standard CMOS devices, serving as a plug-in replacement for LS-TTL devices to reduce power consumption in existing designs. The 74HCT logic family is functionally and pin-out compatible with the standard 74LS logic family. All inputs are protected from static discharge damage by internal diode clamps.
