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 / R ) is high, data flows from the A inputs to the B outputs, and when (T / R ) 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.
Features
