SNJ54AS652W

Overview

The SNJ54AS652W is an octal registered bus transceiver from Texas Instruments' AS series, housed in a 24-lead ceramic dual in-line package (CDIP). It features three-state outputs and supports bidirectional data transfer with integrated latching capabilities. The device operates within a military-grade temperature range of -55°C to 125°C. Key specifications include a load capacitance of 50 pF and inverted output polarity. It utilizes common direction control and is designed for high-reliability applications requiring robust signal integrity.

Feature Summary

• Octal registered bus transceiver architecture providing eight-bit data handling with internal latching
• Three-state outputs enabling direct connection to system buses without additional buffering
• Bidirectional data flow capability controlled by a single direction control input
• Military-grade reliability with extended operating temperature range suitable for harsh environments

Applications

• High-reliability military and aerospace data bus systems
• Industrial control networks requiring isolated bidirectional communication
• Test and measurement equipment interfaces
• Ruggedized computing systems operating in extreme temperatures

Procurement Notes

Verify the specific suffix 'W' indicates the ceramic package variant when sourcing. Confirm RoHS compliance status as indicated in distributor records, noting potential regulatory discrepancies. Ensure the supplier provides traceable documentation for military-grade components. Validate that the received unit matches the 24-lead CDIP physical form factor. Check for any specific handling requirements associated with ceramic packages.

Selection Notes

Select this component when bidirectional data transfer with latching is required in space-constrained or high-vibration environments. The ceramic package offers superior thermal stability compared to plastic variants. Consider the AS series speed characteristics against power consumption needs. Ensure the system voltage levels match the device specifications. Verify that the inverted output polarity aligns with the receiving logic gates.

Part Context

This part belongs to the Texas Instruments SNJ54AS family, which denotes military-grade performance standards. The '54' prefix typically signifies military qualification, while 'AS' indicates the Advanced Schottky logic series. The 'W' suffix specifically identifies the ceramic dual in-line package construction. This family is designed for applications demanding higher reliability than commercial grade parts.

Replacement Considerations

The SNJ54AS652JT is a documented substitute offering identical functional specifications in a similar package configuration. Both parts share the same octal registered bus transceiver functionality and electrical characteristics. Verify pin compatibility and package dimensions before substitution. Ensure the replacement meets the same environmental and reliability standards required by the application.
