SN74HC126DRG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74HC126DRG4 is a quadruple buffer with 3-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and supports an operating temperature range from -40°C to +85°C. The device provides buffered inputs, supports fanout up to 10 LSTTL loads, and offers significant power reduction compared to LSTTL logic ICs.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Contains four independent buffers with 3-state outputs performing the Boolean function Y = A in positive logic.
• Features balanced CMOS 3-state outputs capable of sinking and sourcing similar currents.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the ordering suffix 'G4' corresponds to the specific package and lead finish requirements for your design. Confirm the RoHS compliance status and ensure the SOIC-14 package dimensions match your PCB footprint constraints before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a quadruple non-inverting buffer with high-impedance control is required. Ensure the system supply voltage falls between 2 V and 6 V. Consider the thermal resistance characteristics if multiple channels are active simultaneously to prevent exceeding junction temperature limits.
