HD74LV540A
Octal Inverted Buffers / Drivers with 3-state Outputs
ADE-205-277 (Z)
1st Edition
April 1999
Description
The HD74LV540A has eight inverter drivers with three state outputs in a 20 pin package. When
OE1
and
OE2
is low level, this drivers set up output is enable. Low-voltage operation is suitable for battery-
powered products (e.g., notebook computers), and the low-power consumption extends the battery life.
