HD74LV245A
Octal Bus Transceivers with 3-state Outputs
ADE-205-247 (Z)
1st Edition
March 1999
Description
The HD74LV245A has eight buffers with three-state outputs in a 20-pin package. When DIR is high, data
is transferred from the A inputs to the B outputs, and when DIR is low, data is transferred from the B inputs
to the A outputs. The A and B buses are separated by making the enable input (
OE
) high level. Low-
voltage operation is suitable for battery-powered products (e.g., notebook computers), and the low power
consumption extends the battery life.
