SN74LVC126APWRE4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC126APWRE4 is a quad bus buffer gate with three-state outputs from the Texas Instruments 74LVC family. It operates within a supply voltage range of 1.65V to 3.6V and features inputs that accept voltages up to 5.5V, enabling compatibility in mixed 3.3V and 5V systems. The device provides non-inverting buffering for four independent lines, each controlled by a separate output-enable pin. Packaged in a 14-TSSOP surface-mount format, it supports an industrial operating temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides four independent non-inverting buffer channels with individual output-enable control
• Supports input voltage levels up to 5.5V while operating at lower supply voltages
• Features three-state outputs to prevent bus contention during partial-power-down modes
• Designed for high-speed signal transmission with low power consumption characteristics

Buffers, Drivers, Receivers, Transceivers Applications

• Mixed-voltage level translation between 3.3V and 5V logic domains
• Clock distribution and buffering in telecommunications equipment
• Data bus management in industrial control systems
• Signal isolation in portable computing devices

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'PWRE4' against the manufacturer's current datasheet to confirm package type and RoHS compliance status. Ensure the ordering information matches the required TSSOP-14 configuration. Cross-reference the active status with official Texas Instruments catalogs before finalizing procurement plans.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits requiring interface between 5V tolerant inputs and 3.3V powered buses. The quad configuration reduces board space compared to single-channel alternatives. Verify that the 14-TSSOP package dimensions fit the target PCB layout constraints and thermal requirements.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74LVC126A series of quad bus buffers manufactured by Texas Instruments. The 'E4' suffix typically indicates lead-free and RoHS-compliant manufacturing processes. It serves as a standard logic interface solution for digital systems requiring signal buffering and direction control across multiple data lines simultaneously.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74LVC126APWR is the direct equivalent without the environmental suffix. SN74LVC126ADBR offers the same functionality in a 14-SSOP package. SN74LVC126ARGYR provides identical electrical performance in a 14-VQFN footprint.
