SN74LV157ADRG4

Overview

The SN74LV157ADRG4 is a quadruple 2-line to 1-line data selector/multiplexer from Texas Instruments. It operates within a supply voltage range of 2 V to 5.5 V and accepts input voltages up to 5.5 V. The device features a maximum propagation delay (tpd) of 7.5 ns at 5 V. It provides latch-up performance exceeding 100 mA per JESD 78, Class II standards. The component is housed in a 16-pin SSOP package.

Feature Summary

• Operates with supply voltages ranging from 2 V to 5.5 V
• Inputs accept voltages up to 5.5 V for compatibility
• Provides latch-up protection exceeding 100 mA

Applications

• Servers
• LED Displays
• Network Switches
• Telecom Infrastructure
• Motor Drivers

Procurement Notes

Verify the specific ordering suffix 'RG4' against the manufacturer's current Package Option Addendum to confirm lead finish, moisture sensitivity level, and environmental compliance status. Ensure the selected package type matches the required PCB footprint dimensions and thermal characteristics for the intended application environment.

Selection Notes

Select this component when designing systems requiring low-voltage operation down to 2 V or high-speed multiplexing with delays under 10 ns at 5 V. It is suitable for applications needing inputs that tolerate 5.5 V signals while operating on lower supply rails. Consider the 16-pin SSOP package constraints regarding board space and thermal dissipation requirements.

Part Context

This part belongs to the SN74LV157A family of quadruple 2-line to 1-line data selectors. The family includes variants with different packaging options such as SOIC, TVSOP, SOP, and TSSOP. The 'RG4' suffix typically indicates RoHS-compliant manufacturing and specific material finishes, distinguishing it from standard production versions.

Replacement Considerations

Direct replacements include other SN74LV157A variants with compatible pinouts and electrical specifications. Verify package dimensions and thermal resistance values when substituting between SSOP, SOIC, or TSSOP formats to ensure mechanical fit.
