MM74HC74A
Dual D-Type Flip-Flop with Preset and Clear
General Description
The MM74HC74A utilizes advanced silicon-gate CMOS
technology to achieve operating speeds similar to the
equivalent LS-TTL part. It possesses the high noise immu-
nity and low power consumption of standard CMOS inte-
grated circuits, along with the ability to drive 10 LS-TTL
loads.
This flip-flop has independent data, preset, clear, and clock
inputs and Q and Q outputs. The logic level present at the
data input is transferred to the output during the positive-
going transition of the clock pulse. Preset and clear are
independent of the clock and accomplished by a low level
at the appropriate input.
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
Pb-Free package per JEDEC J-STD-020B.
