SN74LVC126ADR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC126ADR is a quad bus buffer and line driver from Texas Instruments, featuring four non-inverting buffers with independent active-low output enable inputs. It operates within a supply voltage range of 1.65V to 3.6V and supports input voltages up to 5.5V, enabling compatibility in mixed 3.3V and 5V systems. The device utilizes CMOS technology and provides three-state outputs controlled by the nOE pin. It is housed in a 14-pin SOIC package and is rated for an operating temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix against official documentation to confirm package type and temperature rating. Ensure the ordering code matches the required industrial specifications. Confirm RoHS compliance status directly with the manufacturer's current datasheet before procurement to guarantee regulatory adherence.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits requiring signal buffering between different voltage domains. The 5.5V input tolerance allows direct interfacing with legacy 5V logic while operating at lower voltages. Verify that the package dimensions fit the available PCB space and that the thermal characteristics meet the application's environmental requirements.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVC126A family of quad bus buffers. It shares functional similarities with other LVC series devices but is distinguished by its specific package configuration and voltage handling capabilities. The family is designed for high-speed digital applications requiring low power consumption and wide operating voltage flexibility.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for SN74LVC126ADBR or SN74LVC126ARGYR as potential alternatives if package variations are acceptable. Verify electrical parameters and pinout compatibility before substitution.
