SN74LV8T157MPWREP

Overview

The SN74LV8T157MPWREP is an enhanced-product quad 2-input multiplexer with logic-level shifter capabilities, manufactured by Texas Instruments. It operates within a supply voltage range of 1.65 V to 5.5 V and features a TSSOP-20 package. The device supports bi-directional data transfer and includes three-state outputs for bus-oriented applications. It is designed for military-grade reliability with extended temperature ranges from -55°C to +125°C.

Feature Summary

• Integrated logic-level shifting allows seamless interfacing between different voltage domains without external components.
• Enhanced product qualification ensures high reliability for demanding military and aerospace environments.
• Quad configuration provides four independent 2-to-1 multiplexing channels in a compact surface-mount package.

Applications

• Military avionics signal routing
• Aerospace data bus management
• High-reliability industrial control systems

Procurement Notes

Verify the specific suffix 'REP' indicates the required enhanced product qualification level suitable for your application's environmental standards. Confirm that the TSSOP-20 package dimensions match your PCB footprint requirements. Ensure the operating voltage range aligns with your system's power supply specifications before finalizing procurement.

Selection Notes

Select this component when both multiplexing functionality and voltage translation are required in a single integrated circuit. It is appropriate for designs needing robust performance across wide temperature variations. Consider the pin count and package size relative to available board space. Verify compatibility with existing logic families if interfacing with non-LVxT devices.

Part Context

This part belongs to Texas Instruments' LVxT series, which combines low-voltage CMOS technology with TTL-compatible inputs. The 'EP' designation signifies enhanced product status, often implying stricter manufacturing controls or testing protocols compared to standard commercial variants. It serves as a specialized solution for critical infrastructure where failure is not an option.

Replacement Considerations

Check for SN74LV8T157PW as a potential commercial equivalent if military-grade qualification is not required. Verify pinout compatibility and electrical characteristics against any alternative multiplexers with level-shifting capabilities.
