CD74HCT174E Flip-flop D-type, hex, 4.5 ... 5.5 V, DIL-16

High-Speed CMOS Logic Hex D-Type Flip-Flop with Reset

Description The ’HC174 and ’HCT174 are edge triggered flip-flops which utilize silicon gate CMOS circuitry to implement D-type flipflops. They possess low power and speeds comparable to low power Schottky TTL circuits. The devices contain six masterslave flip-flops with a common clock and common reset. Data on the D input having the specified setup and hold times is transferred to the Q output on the low to high transition of the CLOCK input. The MR input, when low, sets all outputs to a low state. Each output can drive ten low power Schottky TTL equivalent loads. The ’HCT174 is functional as well as, pin compatible to the ’LS174.
