MM74C174

Hex D-Type Flip-Flop

General Description

The MM74C174 hex D-type flip-flop is a monolithic comple-

mentary MOS (CMOS) integrated circuit constructed with

N- and P-channel enhancement transistors. All have a

direct clear input. Information at the D inputs meeting the

setup time requirements is transferred to the Q outputs on

the positive-going edge of the clock pulse. Clear is inde-

pendent of clock and accomplished by a low level at the

GND.

Features

s Wide supply voltage range:

3.0V to 15V

s Guaranteed noise margin: 1.0V

s Low power TTL compatibility:

Fan out of 2 driving 74L

Ordering Code:

Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code.
