SN74ALS746N

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALS746N is an octal buffer and line driver manufactured by Texas Instruments. It belongs to the ALS logic series and features eight independent buffers with input pull-up resistors. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports propagation delays up to 18 ns. It is housed in a 20-pin DIP package and functions as a unidirectional data transfer component.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Octal configuration providing eight independent buffer channels
• Integrated input pull-up resistors for stable signal levels
• High-speed operation capability suitable for demanding digital applications

Buffers, Drivers, Receivers, Transceivers Applications

• Bus-oriented memory and address drivers
• Clock drivers for high-capacitance loads
• Line termination circuits requiring noise immunity

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'N' confirms the PDIP-20 through-hole package variant. Confirm RoHS compliance status via the official datasheet, as historical ALS parts may have varying environmental declarations. Ensure the source document explicitly lists this part number to avoid confusion with similar ALS buffer families.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal buffer with built-in pull-ups is required for bus driving or clock distribution. The ALS series offers a balance of speed and power consumption compared to standard TTL. Verify that the 20-pin DIP form factor fits the target PCB layout constraints before finalizing the design.

Buffers, Drivers, Receivers, Transceivers Part Context

This part is part of the Texas Instruments SN74ALS family, which utilizes Advanced Low-power Schottky technology. The SN74ALS746 specifically addresses applications needing multiple buffered outputs with defined input states, distinguishing it from standard tri-state buffers or non-buffered logic gates.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for SN74ALS746DR (SOIC-20) if surface mount is required. Verify compatibility with SN74LS746N for pin-compatible alternatives, noting potential differences in switching speeds and power dissipation characteristics between LS and ALS technologies.
