74LV138PW,118

Signal Switches, Multiplexers, Decoders Overview

The Nexperia 74LV138PW,118 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 and features three enable inputs for parallel expansion or demultiplexing functions. It complies with JEDEC standards JESD8-7, JESD8-5, JESD8C, and JESD36, ensuring compatibility across various voltage levels.

Signal Switches, Multiplexers, Decoders Feature Summary

• Features multiple enable inputs allowing easy parallel expansion to larger decoder configurations
• Capable of functioning as an eight-output demultiplexer by utilizing active LOW enable inputs as data strobes
• Includes input clamp diodes enabling direct interface with voltages exceeding the supply voltage when current limiting resistors are used

Signal Switches, Multiplexers, Decoders Applications

• Memory chip select decoding
• Demultiplexing applications using enable inputs as data strobes
• Parallel expansion of decoder systems to 1-of-32 configurations

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify that the specific ordering suffix matches the required package type, as the base part number covers multiple packages. Confirm the temperature range specification aligns with system requirements, noting this variant supports -40 °C to +125 °C. Ensure design compliance with absolute maximum ratings regarding supply voltage and current limits to prevent permanent damage.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a low-voltage CMOS decoder with wide supply flexibility is required. The TSSOP16 package offers space efficiency compared to standard SO packages. Consider the demultiplexing capability if signal routing control via enable pins is needed. Verify ESD protection requirements against HBM and CDM standards specified in the datasheet.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the 74LV series of logic devices, characterized by operation down to 1.0 V. It is distinct from automotive qualified variants which carry specific Q100 suffixes. The PW suffix specifically denotes the thin shrink small outline plastic package with a 4.4 mm body width, differentiating it from standard SO or DHVQFN options.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Direct substitutes include other 74LV138 variants in compatible packages such as the 74LV138D (SO16). Cross-manufacturer equivalents like the MC74LVX138DTR2G may be considered but require verification of pinout and electrical characteristics.
