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 flip-
flops. 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 com-
mon 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
Each output can drive 10 low power Schottky TTL equiva-
lent loads. The MM74HC273 is functionally as well as pin
compatible to the 74LS273. All inputs are protected from
damage due to static discharge by diodes to VCC and
■ Typical propagation delay: 18 ns
■ Wide operating voltage range
■ Low input current: 1
PA maximum
■ Low quiescent current: 80
PA (74 Series)
■ Output drive: 10 LS-TTL loads
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
