SN74LVC2T45DCTR

The SN74LVC2T45DCTR is a 2-bit Dual Supply Transceiver with configurable voltage-level shifting and 3-state outputs. This dual-bit non-inverting bus transceiver uses two separate configurable power-supply rails. The A port is designed to track VCCA. VCCA accepts any supply voltage from 1.65 to 5.5V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.65 to 5.5V. This allows for universal low-voltage bidirectional translation between voltage nodes. It is designed for asynchronous communication between two data buses. The logic levels of the direction-control (DIR) input activate either the B-port outputs or the A-port outputs. The device transmits data from the A bus to the B bus when the B-port outputs are activated and from the B bus to the A bus when the A-port outputs are activated. The input circuitry on both A and B ports always is active and must have a logic HIGH or LOW level applied to prevent excess ICC and ICCZ.
