DescriptionThe SN74AXC4T245PWR is a four-bit noninverting bus transceiver that uses two individuallyconfigurable power-supply rails. The device is operational with both VCCAand VCCB supplies as low as 0.65 V. The A port is designed to trackVCCA, which accepts any supply voltage from 0.65 V to 3.6 V. The B port isdesigned to track VCCB, which also accepts any supply voltage from 0.65 V to3.6 V. Additionally the SN74AXC4T245PWR is compatible with a single-supply system.
The SN74AXC4T245PWR 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 onthe logic level of the direction-control inputs (1DIR and 2DIR). The output-enable inputs(1OE pins should be tied to VCCA through apullup resistor.
This device is fully specified for partial-power-down applications using theIoff current. The Ioff protection circuitry ensuresthat no excessive current is drawn from or to an input, output, or combined I/O that is biased to aspecific voltage while the device is powered down.
The VCC isolation feature ensures that if eitherVCCA or VCCB is less than 100 mV, both I/O portsenter a high-impedance state by disabling their outputs.
Glitch-Free power supply sequencing allows either supply rail to be powered on or off inany order while providing robust power sequencing performance.
