MM74HC273 Octal D-Type Flip-Flops with Clear September 1983 Revised May 2005 MM74HC273 Octal D-Type Flip-Flops with Clear 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. Each output can drive 10 low power Schottky TTL equivalent loads. The MM74HC273 is functionally as well as pin compatible to the 74LS273.
