SN74ALS466AN

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ALS466AN is an octal bus driver from Texas Instruments' Advanced Low-power Schottky (ALS) logic family. It features inverted outputs and operates within a supply voltage range of 4.5 V to 5.5 V. The device provides low-level output current of 8 mA and high-level output current of -400 uA, with a propagation delay of 18 ns. Designed for through-hole mounting, it is housed in a standard PDIP-20 package and supports operation across a temperature range of 0°C to +70°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Octal configuration providing eight independent bus driver channels
• Inverted output polarity for signal inversion during transmission
• Advanced Low-power Schottky technology ensuring high-speed performance with reduced power consumption
• TTL-compatible input and output interfaces

Buffers, Drivers, Receivers, Transceivers Applications

• Bidirectional data bus driving applications
• Unidirectional bus drivers in digital systems
• Memory interface circuits requiring signal buffering
• General-purpose logic buffering in industrial control equipment

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'AN' confirms the PDIP-20 through-hole package variant. Confirm the ALS series designation matches system requirements for speed and power. Ensure the inverted output characteristic aligns with circuit design needs. Check RoHS compliance status if required by manufacturing standards. Validate supplier authenticity for Texas Instruments components.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal buffer with inverted outputs is required. The ALS series offers a balance of speed and power efficiency suitable for general digital logic. Consider the PDIP-20 package for prototyping or through-hole assembly processes. Verify that the 5V operating voltage and TTL compatibility match the surrounding circuitry constraints.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments SN74ALS74A series, specifically the ALS logic family known for improved speed-over-power characteristics compared to standard LS logic. The SN74ALS466AN serves as an octal buffer, distinct from single-function gates or flip-flops within the same broader logic ecosystem.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74LS466N: Octal buffer with tri-state outputs; verify output type compatibility. SN74ALS466DR: Same functional logic but in SOIC-20 surface-mount package; check footprint requirements.
