SNJ54LS241W

Overview

The SNJ54LS241W is an octal buffer and line driver manufactured by Texas Instruments, belonging to the LS logic series. It features two independent four-bit functions with true outputs and three-state capabilities. The device utilizes a 20-pin ceramic dual flatpack (CDFP-20) package designed for military-grade reliability. It operates within a temperature range of -55°C to 125°C and supports a maximum low-level output current of 12 mA.

Feature Summary

• Provides bidirectional data buffering with three-state outputs for bus-oriented systems
• Features separate enable controls for each of the two four-bit sections
• Constructed in hermetically sealed ceramic packaging for harsh environment durability

Applications

• Military aerospace computing systems requiring high reliability
• Industrial control buses operating in extreme temperatures
• Test and measurement equipment demanding stable signal integrity

Procurement Notes

Verify the specific manufacturer source, as this part may be produced by Texas Instruments or Rochester Electronics. Confirm the package type matches the required CDFP-20 footprint. Ensure compliance with leaded material requirements, as RoHS certification is not applicable to this component. Validate the date code against project lifecycle needs.

Selection Notes

Select this component when designing systems that require robust, isolated buffering for critical data lines. The LS series offers standard speed suitable for general-purpose digital interfaces. Consider the physical size of the 20-pin ceramic package during PCB layout planning. Verify that the power supply voltage aligns with standard TTL levels.

Part Context

This device is part of the broader SN54/74LS241 family of octal buffers. While the SN74 variant targets commercial use, the SNJ prefix indicates a military-grade version with extended temperature ranges. It serves as a unidirectional alternative to transceivers like the SN54LS245, focusing on driving signals rather than bidirectional transfer.
