HD74LV175A
Quad. D-type Flip-Flops with Clear
ADE-205-270 (Z)
1st Edition
April 1999
Description
Information at the D inputs of the HD74LV175A is transferred to the Q and
Q
outputs on the positive going
edge of the clock pulse. Both true and complement outputs from each flip-flop are externally available.
All four flip-flops are controlled by a common clock and common clear. Clearing is accomplished by a
negative pulse at the clear input. All four Q outputs are cleared to a logic low level and all four
Q
outputs
to a logic high level. Low-voltage and high-speed operation is suitable for battery-powered products (e.g.,
notebook computers), and the low-power consumption extends the battery life.
