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.

VCC = 2.0 V to 5.5 V All inputs VIH (Max. ) = 5.5 V (@VCC = 0 V to 5.5 V) All input outputs VI/O (Max. ) = 5.5 V (@VCC = 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 ±24 mA (@VCC = 3.0 V to 5.5 V) Function Table Inputs OE L L H H: L: X: Z: High level Low level Immaterial High impedance T/R L H X Operation B data to A bus A.
