Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging and tape-and-reel specifications. Confirm that the requested quantity aligns with standard shipping units defined in the datasheet. Check for any regional distribution restrictions or RoHS compliance declarations required for your specific manufacturing environment before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring 16-bit parallel data latching with three-state control. It is suitable for applications needing operation between 2.3V and 3.6V with high noise immunity. Consider its pin compatibility with standard 74-series logic if migrating from older designs. Ensure the TSSOP-48 package fits the available PCB footprint and thermal requirements of the target assembly process.

Part Context

This part belongs to the VCX family of advanced high-speed CMOS logic devices. It serves as a digital storage element within broader logic families designed for low-voltage operations. The component complements other bus drivers and buffers in the same series, providing essential data retention capabilities for complex digital architectures requiring synchronized parallel data handling.

Replacement Considerations

Direct substitutes include the 74VCXH16374MTR from STMicroelectronics, which shares identical electrical characteristics but differs in reel packaging configuration. Cross-manufacturer equivalents may exist within the ALVC or LVT families, provided they support 16-bit width, three-state outputs, and compatible operating voltages.
