3 Description

The SN74AXC2T45-Q1 is a two-bit noninverting bus

transceiver that uses two individually configurable

power-supply rails. The device is operational with both

voltage from 0.65 V to 3.6 V. The B port is designed

from 0.65 V to 3.6 V. Additionally the SN74AXC2T45-

Q1 is compatible with a single-supply system.

The SN74AXC2T45-Q1 device is designed for

asynchronous communication between data buses.

The device transmits data from the A bus to the B

bus or from the B bus to the A bus, depending on

the logic level of the direction-control input (DIR). The

SN74AXC2T45-Q1 device is designed so the control

This device is fully specified for partial-power-down

circuitry ensures that no excessive current is drawn

from or to an input, output, or combined I/O that

is biased to a specific voltage while the device is

powered down.

high-impedance state by disabling their outputs.

Glitch-free power supply sequencing allows either

supply rail to be powered on or off in any order while

providing robust power sequencing performance.
