SINGLE-BIT DUAL-SUPPLY BUS TRANSCEIVER 总线收发器

This single-bit noninverting 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 V to 5.5 V. The B port is designed to track
VCCB. VCCB accepts any supply voltage from 1.65 V to 5.5 V. This allows for universal low-voltage bidirectional
translation between any of the 1.8-V, 2.5-V, 3.3-V, and 5-V voltage nodes.

The SN74LVC1T45 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.
