The SN74LVC2T45DCUR is a 2-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 any of the 1.8, 2.5, 3.3 and 5 voltage nodes. The SN74LVC2T45 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.
• DIR Input circuit referenced to VCCA
• Low power consumption
• Ioff Supports partial-power-down mode operation
• Latch-up performance exceeds 100mA per JESD, 78 class II
• ±24mA Output drive at 3.3V
