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.

Notes: The absolute maximum ratings are values which must not individually be exceeded, and furthermore,
no two of which may be realized at the same time.
1. The input and output voltage ratings may be exceeded if the input and output clamp-current
ratings are observed.
2. This value is limited to 5.5 V maximum.
3. The maximum package power dissipation was calculated using a junction temperature of 150
C.
