HD74LVCR2245A Octal Bidirectional Transceivers with 3–state Outputs ADE-205-235A (Z) Preliminary 2nd.
Edition January 1999 Description The HD74LVCR2245A 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.
All outputs, which are designed to sink up to 12 mA, include equivalent 26 Ω resistors to reduce overshoot and undreshoot.
When VCC is between 0 and 1.
5 V, the device is in the high impedance state during power up or power down.
Low voltage and high speed operation is suit...
