Procurement Notes

Verify the specific suffix 'MX' against official datasheets to confirm package type and tape-and-reel specifications. Ensure RoHS compliance status matches current manufacturing standards. Confirm lead-free certification if required by assembly processes. Cross-reference part numbers with onsemi documentation following corporate mergers.

Selection Notes

Select this component when high-speed octal latching is required with low power consumption. It serves as a direct replacement for 74HC273 in designs needing improved switching speeds. Consider the 2.0 V to 5.5 V operating range for flexible voltage domain interfacing. Verify input capacitance and drive requirements for high-frequency signal integrity.

Part Context

This device belongs to the 74VHC series, representing advanced high-speed CMOS logic. It is manufactured by Fairchild Semiconductor, now part of onsemi. The 74VHC family bridges the gap between standard HC speed and lower power consumption, providing robust performance for modern digital applications requiring efficient power management and fast switching times.

Replacement Considerations

The 74VHC273MX is pin-compatible with the 74HC273. Verify that the target application can support the higher speed capabilities without signal integrity issues. Check for equivalent parts from other manufacturers such as NXP or STMicroelectronics if supply constraints exist.
