High-Speed CMOS Logic
Hex D-Type Flip-Flop with Reset
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 鈥橦CT174 is functional as well as, pin
compatible to the 鈥橪S174.

Description
The 鈥橦C174 and 鈥橦CT174 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 鏗俰p-鏗俹ps with a common clock and common reset.
