74LV138PW,112

Signal Switches, Multiplexers, Decoders Overview

The Nexperia 74LV138PW,112 is a 3-to-8 line decoder and demultiplexer housed in a TSSOP16 (SOT403-1) package. It decodes three binary weighted address inputs to eight mutually exclusive active LOW outputs. The device operates on a single supply voltage ranging from 1.0 V to 5.5 V. It features three enable inputs: two active LOW (E1, E2) and one active HIGH (E3). Inputs include clamp diodes for interfacing with voltages exceeding VCC.

Signal Switches, Multiplexers, Decoders Feature Summary

• CMOS low power dissipation optimized for low voltage applications
• Direct interface capability with TTL levels
• Demultiplexing functionality using enable inputs as data strobes
• Multiple input enables allowing easy parallel expansion

Signal Switches, Multiplexers, Decoders Applications

• Memory chip select decoding
• Parallel expansion of decoder systems
• Eight-output demultiplexing circuits

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix '112' corresponds to the TSSOP16 package variant when sourcing. Confirm the temperature range specification matches the design requirements, as this part is specified for operation from -40 °C to +125 °C. Ensure compatibility with the required logic family standards before finalizing procurement.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component for designs requiring wide supply voltage flexibility between 1.0 V and 5.5 V. It is suitable for mixed voltage environments due to direct TTL level interfacing. Consider the TSSOP16 package dimensions if board space allows for slightly larger footprints compared to QFN options.

Signal Switches, Multiplexers, Decoders Part Context

This device belongs to the 74LV series of logic ICs, designed for low-voltage CMOS applications. It functions as a standard 3-to-8 decoder/demultiplexer within the broader Nexperia logic portfolio, providing high noise immunity and latch-up protection compliant with JESD 78 Class II Level B standards.

Signal Switches, Multiplexers, Decoders Replacement Considerations

The 74LV138D,118 serves as a pin-compatible alternative utilizing an SO16 package instead of TSSOP16.
