Description

The SN74AXC4T245 is a four-bit noninverting bus

transceiver that uses two individually configurable

power-supply rails. The device is operational with both

VCCA and VCCB supplies as low as 0.65V. The A port

is designed to track VCCA, which accepts any supply

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

to track VCCB, which also accepts any supply voltage

from 0.65V to 3.6V. Additionally the SN74AXC4T245

is compatible with a single-supply system.

The SN74AXC4T245 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 inputs (1DIR and 2DIR).

The output-enable inputs (1 OE and 2 OE) are used

to disable the outputs so the buses are effectively

isolated. The SN74AXC4T245 device is designed so

the control pins (xDIR and x OE) are referenced to

VCCA.

To put the level shifter I/Os in the high-impedance

state during power up or power down, tie the xOE

pins to VCCA through a pullup resistor.

This device is fully specified for partial-power-down

applications using the Ioff current. The Ioff protection

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.

The design of the VCC isolation feature allows both

I/O ports to enter a high-impedance state by disabling

their outputs if either VCCA or VCCB is less than

100mV.

Glitch-Free power supply sequencing allows either

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

providing robust power sequencing performance.
