Octal Bidirectional Transceivers With 3-state Outputs - Hitachi Semiconductor

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 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 suitable at battery drive product (note type personal computer) and low power consumption extends the life of a battery for long time operation.
