SN74LXCH8T245PWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LXCH8T245PWR is an 8-bit dual-supply translating transceiver from Texas Instruments, designed for asynchronous communication between buses operating at different voltage levels. It features a wide supply voltage range of 1.1V to 5.5V on both ports, enabling flexible interface configurations. The device supports data rates up to 420 Mb/s with a propagation delay of 100 ns. It utilizes a TSSOP-24 package and operates within a temperature range of -40°C to +125°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Dual-supply architecture allows independent voltage configuration for A and B ports across the full 1.1V to 5.5V range.
• Integrated bus-hold circuitry maintains signal states when inputs are floating or disconnected.
• Configurable direction control enables bidirectional data transfer between the two voltage domains.

Buffers, Drivers, Receivers, Transceivers Applications

• Asynchronous communication between system buses operating at different logic voltage levels
• Interface bridging in portable and battery-powered electronic devices
• General-purpose translation between low-voltage and standard-voltage logic circuits

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'PWR' corresponds to the TSSOP-24 package and tape-and-reel shipping format. Confirm that the component meets RoHS compliance requirements for your region. Ensure the ordering quantity aligns with the manufacturer's standard reel size specifications to avoid partial reel handling issues during assembly.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing systems requiring a broad input voltage range starting as low as 1.1V. The LXCH series is suitable for applications prioritizing wide voltage compatibility over ultra-high-speed performance compared to AVC or LVC alternatives. Consider the thermal characteristics and package constraints when designing for high-temperature environments up to 125°C.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LXCH8T245 family of translating transceivers. It shares functional similarities with other 8-bit bus transceivers but is distinct in its extended low-voltage capability down to 1.1V. The PWR suffix specifically denotes the surface-mount TSSOP-24 packaging variant used in compact electronic designs.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include SN74LXCH8T245PW (same function, tube packaging) and SN74LXCH8T245RHLR (QFN package). For higher speed requirements, consider the SN74AVC8T245 series, though voltage ranges differ. Verify pinout compatibility before replacing with non-LXCH variants.
