SNJ54F153W

Signal Switches, Multiplexers, Decoders Overview

The SNJ54F153W is a dual 4-line to 1-line multiplexer from the F/FAST logic family, housed in a 16-pin Ceramic Flatpack (CFP) package. It operates over the military temperature range of -55°C to 125°C with a supply voltage of 4.5V to 5.5V. The device features two independent sections sharing common select inputs A and B. Electrical characteristics include a high-level output voltage of 2.5V minimum at -1mA load and a low-level output voltage of 0.5V maximum at 20mA load. Propagation delays are specified up to 14ns for data paths and 11.5ns for strobe paths.

Signal Switches, Multiplexers, Decoders Feature Summary

• Provides full binary decoding via integrated inverters and drivers to support AND-OR gate selection
• Features separate strobe (enable) inputs for each of the two 4-line sections
• Supports cascading configurations for N-lines to N-lines multiplexing

Signal Switches, Multiplexers, Decoders Applications

• Multiplexing from N lines to one line
• Parallel-to-serial data conversion
• Cascaded multiplexing systems

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify that the component matches the specific SNJ54F153W part number and CFP-16 package configuration. Confirm the manufacturer origin and check for any required military qualification certifications such as QML or JM38510 standards. Ensure the operating temperature range requirements align with the specified -55°C to 125°C limits before procurement.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a dual 4-to-1 multiplexer with military-grade temperature stability is required. The shared select inputs simplify control logic for paired channels. Consider the ceramic flatpack package for hermetic sealing needs in harsh environments. Verify that the propagation delay specifications meet the system timing constraints.

Signal Switches, Multiplexers, Decoders Part Context

This device belongs to the Texas Instruments SN54F series, designed for high-speed digital applications requiring robust performance across extreme temperatures. The 'J' suffix indicates a ceramic dual in-line package, while 'W' denotes the ceramic flatpack variant. Both variants share identical electrical characteristics and functionality within the military specification framework.

Signal Switches, Multiplexers, Decoders FAQ

What is the function of the G input?

The G input serves as a strobe or enable line. When active, it allows the selected data input to pass to the output; otherwise, the output is disabled.

Are the select inputs shared between the two sections?

Yes, select inputs A and B are common to both multiplexer sections, allowing synchronized selection of data sources for both outputs.
