HD74LVCZ245A Overview
The HD74LVCZ245A 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.
HD74LVCZ245A Key Features
- VCC = 2.7 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 impedance state during power up and power down
- Power off disables outputs, permitting live insertion
- High output current ±24 mA (@V CC = 3.0 to 5.5 V)
