Description
The ’HC174 and ’HCT174 are edge triggered flip-flops which
utilize silicon gate CMOS circuitry to implement D-type flip-
flops. They possess low power and speeds comparable to low
power Schottky TTL circuits. The devices contain six master-
slave 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.
