General Description

The MM74HC273 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 8 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.

Features

■ Typical propagation delay: 18 ns

■ Wide operating voltage range

■ Low input current: 1 μA maximum

■ Low quiescent current: 80 μA (74 Series)

■ Output drive: 10 LS-TTL loads
