HD74LV20A
Dual 4-input Positive NAND Gates
REJ03D0236–0300Z
(Previous ADE-205-254A (Z))
Rev.3.00
May 31, 2004
Description
The HD74LV20A performs the Boolean functions Y =
A•B•C•D
or Y =
A+B+C+D
in positive logic.
Low-voltage and high-speed operation is suitable for the 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 even 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.
