SNJ54ALS244CW

Overview

The SNJ54ALS244CW is an octal buffer and line driver featuring three-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating free-air temperature range from -55 °C to 125 °C. The device utilizes Advanced Low-Power Schottky (ALS) technology with PNP inputs to reduce DC loading. It provides symmetrical active-low output-enable inputs for bus-oriented applications.

Feature Summary

• Octal buffers and line drivers designed for memory address drivers, clock drivers, and bus-oriented receivers
• Three-state outputs capable of driving bus lines or buffering memory address registers
• PNP inputs utilized to reduce DC loading on the driving circuitry

Applications

• Memory address drivers
• Clock drivers
• Bus-oriented receivers and transmitters

Procurement Notes

Verify that the specific ordering suffix 'CW' corresponds to the Ceramic Flat Pack (CFP) package variant as listed in the official Package Option Addendum. Confirm military qualification status and RoHS exemption details directly with the manufacturer, as these specifications are critical for procurement compliance and application suitability.

Selection Notes

Select this component when designing systems requiring high-density octal buffering with low DC loading characteristics. Ensure the design environment accommodates the specified -55 °C to 125 °C operating temperature range. Verify that the CFP package form factor aligns with the target printed circuit board layout and mounting requirements.

Part Context

This part belongs to the SN54ALS244 family of octal buffers and line drivers. It shares functional similarities with the SN54AS244A but differs in electrical characteristics and speed parameters. The SN54 prefix indicates military-grade qualification, distinguishing it from commercial variants like the SN74ALS244C.

Replacement Considerations

Public confirmed substitute part numbers include SNJ54ALS244CJ and SNJ54ALS244CFK.
