HD74LVCR2245A 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.
HD74LVCR2245A Key Features
- 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
