74VHC157SJX

Signal Switches, Multiplexers, Decoders Overview

The onsemi 74VHC157SJX is a Quad 2-Input Multiplexer fabricated with advanced high-speed silicon gate CMOS technology. It provides four independent 2-channel multiplexers sharing common Select and Enable inputs. The device operates within a DC supply voltage range of 2.0 V to 5.5 V and supports an operating temperature range from -40°C to +85°C. It features input protection allowing 0 V to 5.5 V application regardless of supply voltage, enabling safe interfacing between 5 V and 3 V systems.

Signal Switches, Multiplexers, Decoders Feature Summary

• Provides high-speed digital switching performance comparable to Bipolar Schottky TTL while maintaining low CMOS power dissipation.
• Includes input protection circuits that prevent device destruction caused by mismatched supply and input voltages during system interfacing.
• Features active-low Enable functionality that forces all outputs to a LOW level when the input is held HIGH, inhibiting data selection.

Signal Switches, Multiplexers, Decoders Applications

• Moving data between two groups of registers to four common output buses under Select control.
• Implementing gating functions by generating specific logic functions of two variables where one variable is common.
• Interfacing 5 V logic systems with 3 V logic systems or battery backup architectures.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the package suffix 'SJX' against official documentation, as standard listings typically utilize 'MX', 'MTCX', or 'DT'. Confirm the specific package type corresponds to your design requirements. Ensure compatibility with the 74VHC series electrical specifications before finalizing procurement orders for production integration.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when designing circuits requiring quad 2-input multiplexing with shared control lines. It is suitable for applications demanding high noise immunity and low power consumption in portable or battery-operated equipment. Verify that the required propagation delay and output drive current meet the system timing and load constraints defined in the datasheet.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the 74VHC family of advanced high-speed CMOS logic devices manufactured by onsemi. The family is designed to offer performance levels similar to Bipolar Schottky TTL but with significantly lower power dissipation. These components are widely used in general-purpose digital logic applications requiring reliable signal routing and switching capabilities.

Signal Switches, Multiplexers, Decoders Replacement Considerations

The 74VHC157MTCX (TSSOP-16) and 74VHC157MX (SOIC-16) are documented equivalents within the same product line. Verify pinout and electrical characteristics match before substitution. Cross-reference with other manufacturers' 74VHC157 variants only if functional and mechanical compatibility is confirmed.
