The HD74ALVC166245A has 16 bus transceivers with three state outputs in a 48-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 16-bit non-inverting bus transceiver uses two separate power-supply rails.
And this product has two terminals (VCCA, VCCB), VCCA is connected with A bus side, VCCB is connected with control input and B bus. VCCA and VCCB are isolated.
The A port is designed to track VCCA, which accepts voltages from 1.2 V to 2.7 V, and the B port is designed to track VCCB, which operates at 1.4 V to 3.6 V. Therefore, Bidirectional broad voltage conversion is possible.
Low voltage and high-speed operation is suitable at the battery drive product (note type personal puter) and low power consumption extends the life of a battery for long time operation.
