Procurement Notes

Verify that the ordering suffix '-Q' corresponds to the specific automotive qualification requirements, including unique site and control change protocols. Confirm package type matches SC-74A specifications. Ensure compliance with RoHS and halogen-free material standards as documented in the datasheet.

Selection Notes

Select this component when a single-channel non-inverting buffer with open-drain output is required. It is suitable for designs needing over-voltage tolerance on I/O lines while operating from a 2.0 V to 5.5 V supply. Consider the SC-74A package size for space-constrained PCB layouts.

Part Context

This device belongs to the MC74VHC1G series of advanced high-speed CMOS buffers. It shares functional similarities with the MC74VHC1GT07 but differs in input threshold levels; the G07 uses CMOS-level thresholds while the GT07 uses TTL-level thresholds. Both offer similar speed and power characteristics.
