HD74LV245A Octal Bus Transceivers with 3-state Outputs

The HD74LV245A has eight buffers with three-state outputs in a 20-pin package. When DIR is high, data is transferred from the A inputs to the B outputs, and when DIR is low, data is transferred from the B inputs to the A outputs. The A and B buses are separated by making the enable input (OE) high l.

HD74LV245A Features

* VCC = 2.0 V to 5.5 V operation All inputs VIH (Max.) = 5.5 V (@VCC = 0 V to 5.5 V) All outputs VO (Max.) = 5.5 V (@VCC = 0 V) Typical VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25°C) Typical VOH undershoot > 2.3 V (@VCC = 3.3 V, Ta = 25°
