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.
