74AVCH1T45GN,132

Overview

The Nexperia 74AVCH1T45GN,132 is a single-bit dual-supply voltage level translator and transceiver housed in an XSON6 (SOT1115) package. It supports bidirectional data translation with supply voltages ranging from 0.8 V to 3.6 V on both ports A and B. The device features three-state outputs, active bus hold circuitry, and IOFF for partial power-down protection. It complies with JEDEC standards including JESD8-12 through JESD8C. Operating temperatures range from -40 °C to +125 °C.

Feature Summary

• Active bus hold circuitry maintains valid logic levels on floating or unused inputs without external resistors
• IOFF circuitry disables outputs during partial power-down to prevent damaging backflow current
• Overvoltage tolerant inputs allow operation with signals up to 3.6 V regardless of supply state
• Complies with multiple JEDEC standards covering voltage ranges from 0.8 V to 3.6 V

Applications

• Bidirectional logic level shifting between systems operating at different voltage domains
• Unidirectional logic level-shifting applications requiring controlled directionality
• Partial power-down mode operations where one supply rail is inactive

Procurement Notes

Verify the specific ordering suffix matches the required package variant, as the 74AVCH1T45 family includes TSSOP6, XSON6, and other packages. Confirm the temperature grade corresponds to design requirements, noting that the GN suffix indicates the -40 °C to +125 °C range. Ensure compatibility with system ground references before integration.

Selection Notes

Select this component when interfacing low-voltage logic with higher voltage nodes within the 0.8 V to 3.6 V range. The integrated bus hold feature simplifies design by eliminating pull-up or pull-down resistor requirements. Consider the IOFF capability if the application involves hot-swap scenarios or partial power states to protect downstream components from back-powering.

Part Context

This device belongs to the 74AVCH1T45 family of dual-supply translators manufactured by Nexperia. It is part of the Advanced Very-low-voltage CMOS (AVC) logic series, designed for high-speed data transmission in space-constrained applications. The XSON6 package offers a compact footprint suitable for modern PCB layouts requiring minimal board space.
