HD74LVC245A

Octal Bidirectional Transceivers with 3-state Outputs

ADE-205-111B(Z)

3rd Edition

December 1996

Description

The HD74LVC245A has eight buffers with three state outputs in a 20 pin package. When (T /

is high,

data flows from the A inputs to the B outputs, and when (T /

is low, data flows from the B inputs to the

A outputs. A and B bus are separated by making enable input (OE) high level. Low voltage and high

speed operation is suitable at the battery drive product (note type personal computer) and low power

consumption extends the life of a battery for long time operation.
