CVMEH22501AIDGVREP

Universal Bus Functions Overview

The CVMEH22501AIDGVREP is a Mil Enhanced Universal Bus Transceiver from the SN74VMEH22501A series by Texas Instruments. It features an 8-bit bidirectional bus transceiver with common control and two additional 1-bit transceivers, housed in a 48-pin TSSOP package. The device operates within a supply voltage range of 3.15 V to 3.45 V. It supports LVTTL and TTL input levels with corresponding output levels. Key electrical parameters include a propagation delay of 10.5 ns, high-level output current of -48 mA, and low-level output current of 64 mA. The component functions as a registered bus transceiver with three-state outputs.

Universal Bus Functions Procurement Notes

Verify the specific suffix 'REP' against official manufacturer documentation to confirm Mil Enhanced status and RoHS compliance details. Ensure the ordering part number matches the exact package variant required for your PCB footprint. Cross-reference the datasheet revision date to validate all electrical characteristics before finalizing procurement specifications.

Universal Bus Functions Selection Notes

Select this component when designing systems that require MIL-spec qualified logic interfaces. The narrow 3.15 V to 3.45 V supply range necessitates precise power regulation. Consider the 48-pin TSSOP package dimensions for thermal management and board space constraints. Verify compatibility with existing LVTTL/TTL signaling standards in the target architecture.

Universal Bus Functions Part Context

This part belongs to the SN74VMEH22501A family of universal bus functions. It serves as a specialized version of standard bus transceivers, tailored for environments demanding higher reliability. The device integrates multiple transceiver channels into a single compact package, reducing component count in complex digital interconnect designs.

Universal Bus Functions Replacement Considerations

Check for SN74VMEH22501ADGGR or similar variants if the Mil Enhanced designation is not strictly required. Confirm pinout compatibility before substituting with other 48-pin TSSOP bus transceivers.
