CLVCH16T245MDGVREP

Overview

The CLVCH16T245MDGVREP is a 16-bit dual-supply bus transceiver with configurable voltage levels, manufactured by Texas Instruments. It operates within a supply voltage range of 1.65 V to 3.6 V and supports data rates up to 500 Mbps. The device features a propagation delay of 8.2 ns and functions across an extended temperature range from -55°C to +125°C. Packaged in a 48-pin TVSOP, it provides bidirectional data transmission between buses operating at different voltage domains.

Feature Summary

• Configurable dual-supply architecture allowing independent voltage rails for A and B ports
• Bidirectional data transmission capability between disparate voltage domains
• Extended industrial temperature rating suitable for harsh environments

Applications

• High-speed data translation between low-voltage processors and higher-voltage peripherals
• Memory interface bridging in embedded systems
• Industrial control systems requiring robust signal integrity over wide temperature ranges

Procurement Notes

Verify the specific suffix MDGVREP against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with your system's voltage requirements before integration. Cross-reference part numbers carefully as minor suffix changes may indicate different packaging or testing standards. Confirm RoHS compliance status directly with official documentation prior to procurement.

Selection Notes

Select this component when interfacing 16-bit buses with differing voltage levels requiring high-speed performance. The LVCH series offers lower power consumption compared to standard CMOS alternatives. Consider the TVSOP package constraints regarding thermal dissipation and PCB space. Verify that the 500 Mbps data rate meets your system's timing requirements and that the extended temperature range aligns with your operational environment.

Part Context

This part belongs to Texas Instruments' CLVCH family of level translators. It shares functional similarities with the SN74LVCH16T245 series but includes specific enhancements for reliability and environmental tolerance. The device is designed to facilitate seamless communication between modern low-voltage logic and legacy or higher-voltage components in complex electronic architectures.

Replacement Considerations

The SN74LVCH16T245DGGR is a commercial-grade equivalent with similar electrical characteristics but a narrower operating temperature range (-40°C to +85°C). Verify pinout compatibility and ensure the application does not require the extended temperature rating provided by the CLVCH variant.
