FAIRCHILD MM74HC174SJ

Revised February 1999
MM74HC174
Hex D-Type Flip-Flops with Clear
General Description
The MM74HC174 edge triggered flip-flops utilize advanced
silicon-gate CMOS technology to implement D-type flipflops. They possess high noise immunity, low power, and
speeds comparable to low power Schottky TTL circuits.
This device contains 6 master-slave flip-flops with a common clock and common clear. 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 CLEAR input when LOW, sets all outputs to a low
state.
Each output can drive 10 low power Schottky TTL equivalent loads. The MM74HC174 is functionally as well as pin
compatible to the 74LS174. All inputs are protected from
damage due to static discharge by diodes to VCC and
ground.
Features
■ Typical propagation delay: 16 ns
■ Wide operating voltage range: 2–6V
■ Low input current: 1 µA maximum
■ Low quiescent current: 80 µA (74HC Series)
■ Output drive: 10 LSTTL loads

Note 4: For a power supply of 5V ±10% the worst case output voltages (VOH, and VOL) occur for HC at 4.5V. Thus the 4.5V values should be used when
designing with this supply. Worst case VIH and VIL occur at VCC = 5.5V and 4.5V respectively. (The VIH value at 5.5V is 3.85V.) The worst case leakage current (IIN, ICC, and IOZ) occur for CMOS at the higher voltage and so the 6.0V values should be used.
