MM745HC174 Hex D-Type Flip-Flops with Clear January 2009 MM74HC174 Hex D-Type Flip-Flops with Clear Features Description The MM74HC174 edge-triggered flip-flops utilize Typical Propagation Delay: 16ns silicon-gate CMOS technology to implement D-type flip- Wide Operating Voltage Range: 2V6V flops. They possess high noise immunity, low-power, and speeds comparable to low-power Schottky TTL Low Input Current: 1A maximum circuits. This device contains six master-slave flip-flops Low Quiescent Current: 80A (74HC Series) with a common clock and common clear. Data on the D input with the specified setup and hold times is Output Drive: 10 LSTTL Loads transferred to the Q output on the LOW-to-HIGH transition of the CLOCK input. When LOW, the input sets all outputs to a LOW state. Each output can drive ten low-power Schottky TTL equivalent loads. The MM74HC174 is functionally and pin comparable to the 74LS174. All inputs are protected from damage due to static discharge by diodes to V CC and ground.
