74LVCH8T245PW-Q10J

Overview

The Nexperia 74LVCH8T245PW-Q10J is an 8-bit dual supply translating transceiver with 3-state outputs, housed in a TSSOP24 package (SOT355-1). It supports bidirectional level translation between any low voltage nodes ranging from 1.2 V to 5.5 V on both VCC(A) and VCC(B). The device features active bus hold circuitry, IOFF for partial power-down, and AEC-Q100 Grade 1 qualification. Operating temperatures extend from -40 °C to +125 °C.

Feature Summary

• Automotive grade qualification compliant with AEC-Q100 Grade 1 standards
• Active bus hold circuitry maintains valid logic levels for unused or floating inputs
• IOFF circuitry prevents damaging backflow current during partial power-down states
• Dual supply architecture enables flexible translation across mixed voltage domains

Applications

• Automotive electronic systems requiring robust signal translation
• Mixed voltage interface circuits connecting disparate logic levels
• Partial power-down applications utilizing IOFF functionality
• Bidirectional data buses operating within specified temperature ranges

Procurement Notes

Verify the specific ordering suffix matches the required package variant and temperature range. Confirm that the component meets AEC-Q100 Grade 1 requirements for your target application. Ensure compatibility with existing PCB footprints for the TSSOP24 form factor before finalizing procurement decisions.

Selection Notes

Select this component when automotive reliability and wide voltage translation are critical. The LVCH series offers high noise immunity compared to standard LVC variants. Consider the TSSOP24 package constraints regarding thermal dissipation and board space availability during the design phase.

Part Context

This part belongs to the Nexperia 74LVC(LV)H8T245-Q100 family of octal bus transceivers. It shares functional similarities with the 74LVC8T245 variant but includes enhanced bus hold features characteristic of the LVCH series. Both variants share identical pinouts and core electrical specifications.

Replacement Considerations

The 74LVC8T245PW-Q100 serves as a direct functional substitute lacking the bus hold feature. Verify that the absence of active bus hold does not compromise signal integrity in the target design environment.
