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 1.65V to 5.5V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.65V to 5.5V. This allows for universal low-voltage bidirectional translation between any of the 1.8V, 2.5V, 3.3V, and 5V 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. The input circuitry is always active on both A and B ports and must have a logic HIGH or LOW level applied to prevent excess ICC and ICCZ.
The SN74LVC1T45 is designed so that the DIR input is powered by
VCCA. This device is fully specified for
partial-power-down applications using Ioff. The
Ioff circuitry disables the outputs, preventing
damaging current backflow through the device when it is powered
down. The VCC isolation feature is designed so that if
either VCC input is at GND, then both ports are in the
high-impedance state.
NanoFree™ package technology
is a major breakthrough in IC packaging concepts, using the die as
the package.
