Description
The Harris CD74HC174 and CD74HCT174 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 CD74HCT174 is functional as well as,
pin compatible to the 74LS174.
