SN74LVC1T45DRLR Datasheet PDF - TI

●The SN74LVC1T45DRLR is a single-bit dual-supply Bus Transceiver with configurable voltage-level shifting and 3-state outputs. This 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 1.8/2.5/3.3/5V 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.

● VCC Isolation - If either VCC input Is at GND, both ports are in the high-impedance state

● DIR Input circuit referenced to VCCA

● IOFF Supports partial-power-down mode operation

● Support high speed translation

● Latch-up performance exceeds 100mA per JESD 78, class II

● 4µA ICC Low power consumption

● ±24mA Output drive at 3.3V

● Green product and no Sb/Br
