Additional preview pages of the HD74LVCR2245A datasheet.

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.

VCC = 1.65 to 5.5 V.
All inputs VIH (Max) = 5.5 V (@VCC = 0 to 5.5 V).
All inputs / outputs V I / O (Max) = 5.5 V (@V CC = 0 V or output off state).
Typical VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25°C).
Typical VOH undershoot > 2.0 V (@VCC = 3.3 V, Ta = 25°C).
High output current ±12 mA (@V CC = 3.0 to 5.5 V).
All outputs have equivalent 26 Ω series resistors, so no external resistors are required HD74LVCR2245A Function Tabl.
