SN74LS126ANSR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LS126ANSR is a quad bus buffer manufactured by Texas Instruments, belonging to the 74LS logic series. It features four non-inverting buffers with three-state outputs housed in a 14-SOIC package. The device operates within a supply voltage range of 4.75V to 5.25V and supports an operating temperature range of 0°C to 70°C. Key electrical characteristics include a high-level output current of 2.6mA and a low-level output current of 24mA.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides four independent non-inverting buffer channels for signal transmission.
• Features three-state outputs allowing multiple drivers to share a common data bus.
• Compatible with standard TTL logic levels for interfacing applications.

• Bus-oriented memory and address decoding systems
• Clock drivers and buffered oscillators
• Transceiver buses

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'ANSR' corresponds to the tape-and-reel packaging format and SOIC-14 body style. Confirm RoHS compliance status as manufacturing processes may evolve. Ensure the intended application environment remains within the specified 0°C to 70°C temperature range for reliable operation.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing between 5V logic families requiring bus isolation. The LS series offers moderate speed suitable for general-purpose digital circuits. Consider alternative packages if surface area constraints differ from the standard SOIC dimensions.

Buffers, Drivers, Receivers, Transceivers Part Context

This part is part of the SN54/74(LS)126/25(A) family, which includes similar quad bus buffers. The 'LS' designation indicates Low-power Schottky technology, balancing power consumption and switching speed. It serves as a foundational component in legacy and mixed-signal digital designs.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct functional equivalents include SN74LS126N (through-hole) or SN74LS125ANSR (inverting variant). Verify pin compatibility and output polarity before substitution.
