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 /
5
) is high,
data flows from the A inputs to the B outputs, and when (T /
5
) is low, data flows from the B inputs to
the A outputs. A and B bus are separated by making enable input (
2(
) 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.
