Octal Bidirectional Transceivers with 3- state Outputs
ADE-205-235A (Z) Preliminary 2nd. Edition January 1999 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. All outputs, which are designed to sink up to 12 mA, include equivalent 26 Ω resistors to reduce overshoot and undreshoot. When VCC is between 0 and 1.5 V, the device is in the high impedance state during power up or power down. Low voltage and high speed operation is...
