Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DG4' against current manufacturer documentation to confirm availability status, as this indicates a lead-free RoHS-compliant variant. Ensure the 14-SOIC package dimensions match the design footprint requirements. Cross-reference the datasheet revision history for any updates to electrical characteristics or recommended operating conditions prior to final procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring quadruple buffering with three-state control capabilities. It is suitable for applications needing operation at lower voltages down to 2V compared to standard 5V-only logic families. Consider the 14-SOIC package constraints regarding board space and thermal dissipation. Verify that the input voltage levels are compatible with the system's logic thresholds.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74HC series of high-speed CMOS logic devices produced by Texas Instruments. The HC series offers performance comparable to the older LS-TTL family but with significantly lower power consumption and wider voltage tolerance. The SN74HC126 specifically functions as a quad bus buffer, distinguishing it from other logic gates like NAND or XOR within the same product line.
