Octal Bus Transceiver with adjustable Output Voltage and 3-state Outputs

The HD74LVCC3245A has eight bus transceivers with three state outputs in a 24 pin package. When (DIR) is high, data flows from the A inputs to the B outputs, and when (DIR) 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. This 8-bit non-inverting bus transceiver contains two separate power-supply rails. And this product has two terminals (VCCA, VCCB), VCCA is connected with control input and A bus side, VCCB is connected with B bus side. VCCA and VCCB are isolated. The B port is designed to track VCCB, which accepts voltage from 3 V to 5. 5 V, and the A port is designed to track VCCA, which operates at 2. 3 V to 3. 6 V. This allows for translation from a 3. 3 V to a 5 V system environment and vice versa, or from a 2. 5 V to a 3. 3 V system environment and vice versa. Low voltage and high-speed operation is suitable at the battery drive product (note type personal computer) and low power consumption extends the life of a battery for long time operation.
