Description

General part information

74AXC1T45 Series

The SN74AXC1T45-Q1 is AEC-Q100 qualified single-bit non-inverting 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 SN74AXC1T45-Q1 is compatible with a single-supply system.

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

This device is fully specified for partial-power-down applications using the Ioff current. The Ioff protection circuitry is designed so 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.
