74F157ASJX

Signal Switches, Multiplexers, Decoders Overview

The onsemi 74F157ASJX is a high-speed quad 2-input multiplexer housed in a 16-lead Small Outline Package (SOP). It selects four bits of data from two sources using common Select and Enable inputs, presenting the selected data in true form. The device operates with a supply voltage range of +4.5V to +5.5V and supports an ambient temperature range of 0°C to +70°C. Propagation delays are specified at 3.0ns to 8.0ns for Select-to-Output transitions.

Signal Switches, Multiplexers, Decoders Feature Summary

• Provides four independent 2:1 multiplexing channels controlled by shared Select and Enable signals
• Outputs present selected data in non-inverted form for direct logic interfacing
• Capable of generating any four of sixteen functions of two variables for irregular logic implementation

Signal Switches, Multiplexers, Decoders Applications

• Moving data between two groups of registers to common output busses
• Implementing highly irregular logic functions as a function generator
• High-speed digital signal routing in industrial control systems

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify that the ordering suffix 'X' corresponds to tape and reel packaging rather than tube or tray formats. Confirm the package designation matches the M16D SOP specification. Ensure the component meets the required operating temperature range for the specific application environment before finalizing procurement.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a high-speed quad multiplexer is required within standard 5V logic families. The SOP package offers a compact surface-mount solution suitable for space-constrained designs. Verify that the input/output current capabilities align with the driving and loading requirements of the connected circuitry.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the 74F157A series of quad 2-input multiplexers originally developed by Fairchild Semiconductor. The 'ASJX' designation specifically identifies the 16-lead SOP variant supplied in tape and reel format. The series is characterized by high-speed operation compatible with standard TTL logic levels.
