SN74LS125ANS

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LS125ANS is a quadruple bus buffer with three-state outputs manufactured by Texas Instruments. It belongs to the LS logic series and operates within a supply voltage range of 4.75 V to 5.25 V. The device features four non-inverting channels, each with independent control inputs. Outputs provide low impedance when enabled and high-impedance states when disabled. It is housed in a 14-pin plastic dual in-line package (PDIP) and supports an operating temperature range from 0°C to 70°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Features three-state outputs that present a high-impedance state to the bus when disabled, preventing significant loading or driving interference.
• Provides separate control for each channel, allowing individual enablement or disablement of the four buffers.
• Outputs exhibit low impedance characteristics when enabled, permitting the driving of heavily loaded bus lines without external pullup resistors.

Buffers, Drivers, Receivers, Transceivers Applications

• Bus-oriented memory and signal switching applications
• Clock drivers and buffer circuits
• Multiple transceiver buses

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'ANS' corresponds to the SOP package variant listed in the Package Option Addendum. Confirm RoHS compliance status and lead finish details against current manufacturer documentation. Ensure the procurement source provides valid traceability for this component type.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring quadruple buffering with independent channel control. Verify compatibility with standard TTL logic levels and ensure the application environment remains within the specified commercial temperature limits. Consider the physical package dimensions during PCB layout planning.

Buffers, Drivers, Receivers, Transceivers Part Context

This part is part of the SN54/74LS125A family of quadruple bus buffers. It shares functional similarities with other variants in the series but differs in packaging and environmental specifications. The SN74LS125ANS specifically denotes the surface-mount small outline package version of the LS technology buffer.
