Description

The SN74AXCH1T45DBVR is a single-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 SN74AXCH1T45DBVR is compatible with a single-supply system.

The DIR pin determines the direction of signal propagation. With the DIR pin configuredHIGH, translation is from Port A to Port B. With DIR configured LOW, translation is from Port B toPort A. The DIR pin is referenced to VCCA, meaning that its logic-high andlogic-low thresholds track with VCCA.

Active bus-hold circuitry holds unused or undriven inputs at a valid logic state. Use ofpullup or pulldown resistors with the bus-hold circuitry is not recommended. If a supply is presentfor VCCA or VCCB, the bus-hold circuitry alwaysremains active on the A or B inputs respectively, independent of the state of the direction controlpin.

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.
