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.
