SN74HC126PWTG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74HC126PWTG4 is a quadruple bus buffer gate 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 features buffered inputs, balanced CMOS outputs capable of driving up to 10 LSTTL loads, and 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 that allow similar sourcing and sinking currents
• Includes standard CMOS inputs characterized by high impedance and defined input capacitance
• Equipped with positive and negative clamping diodes on all inputs and outputs

Buffers, Drivers, Receivers, Transceivers Applications

• Enabling digital signals
• Controlling data buses via output enable signals
• Disabling circuitry connected to outputs for power saving

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package type and thermal characteristics against the datasheet requirements. Confirm the RoHS compliance status and lead finish details for the G4 suffix. Ensure the ordering information matches the current orderable addendum provided by Texas Instruments to avoid discrepancies in packaging or availability.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a quadruple non-inverting buffer with 3-state control is required. It is suitable for applications needing wide voltage operation between 2 V and 6 V. Consider the TSSOP-14 package dimensions and thermal resistance values if thermal management is a design constraint. Verify input transition time requirements to prevent excessive current consumption.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SNx4HC126 family of quadruple buffers with 3-state outputs. It is part of the broader HC/UH logic series designed for general-purpose digital applications. The device provides a cost-effective solution for signal buffering and bus driving tasks in CMOS-based systems.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements include other SN74HC126 variants with different packages such as SN74HC126D (SOIC), SN74HC126DB (SSOP), or SN74HC126N (PDIP). Ensure the substitute part maintains the same 3-state functionality and voltage specifications.
