SN74LS126AN

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LS126AN is a quadruple bus buffer manufactured by Texas Instruments, belonging to the 74LS logic series. It features four non-inverting drivers with three-state outputs housed in a 14-pin DIP 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. High-level output current is specified at 2.6mA, while low-level output current reaches 24mA.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides four independent non-inverting buffer channels for signal transmission
• Features three-state outputs allowing connection to shared data buses
• Compatible with standard TTL logic families through LS series characteristics

Buffers, Drivers, Receivers, Transceivers Applications

• Data bus buffering in microprocessor systems
• Isolation between different logic circuits
• Driving high-capacitance loads on digital lines

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'AN' indicates a plastic DIP package when sourcing. Confirm RoHS compliance status as older LS series parts may vary. Check manufacturer documentation for lead times and availability since this component type may be subject to discontinuation notices or lifecycle changes.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this part when non-inverting buffering with tri-state capability is required for 5V TTL applications. Ensure the DIP package format fits the target PCB layout. Compare against SN74LS125 if inverting functionality is acceptable, or consider AHC series for lower power consumption requirements.

Buffers, Drivers, Receivers, Transceivers Part Context

This component is part of the SN54/74(LS)126/25(A) family documented in Texas Instruments datasheets. It serves as a standard interface buffer within legacy digital design architectures. The LS designation indicates Low-power Schottky technology, balancing speed and power dissipation for general-purpose logic applications.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74LS126AD is a pin-compatible alternative with SOIC packaging. SN74LS125ANSR offers similar buffering but with inverting logic function. Verify electrical parameters match before substituting.
