74HC138PW,118

Signal Switches, Multiplexers, Decoders Overview

The Nexperia 74HC138PW,118 is a 3-to-8 line decoder and demultiplexer housed in a TSSOP16 package. It decodes three binary weighted address inputs (A0, A1, A2) to eight mutually exclusive active LOW outputs (Y0 to Y7). The device features three enable inputs: two active LOW (E1, E2) and one active HIGH (E3). It operates on a supply voltage range of 2.0 V to 6.0 V with an operating temperature range from -40 °C to +125 °C.

Signal Switches, Multiplexers, Decoders Feature Summary

• CMOS low power dissipation and high noise immunity
• Demultiplexing capability using active LOW enable inputs as data input
• Multiple input enable for easy parallel expansion to larger decoders
• Inputs include clamp diodes for interfacing voltages exceeding VCC

Signal Switches, Multiplexers, Decoders Applications

• Memory chip select decoding
• Parallel expansion to 1-of-32 decoders
• Eight output demultiplexer configurations

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm that the component meets the necessary environmental standards for the intended application. Check the most recent product status documentation to ensure availability and compliance with current specifications before finalizing procurement plans.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a wide supply voltage range and high noise immunity are required. It is suitable for designs needing multiple enable inputs for complex decoding or demultiplexing tasks. Ensure the design accommodates the specified temperature range and power dissipation limits for reliable operation.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the 74HC logic family, characterized by CMOS technology. It is functionally compatible with other 74HC series devices but offers specific decoding capabilities. The PW suffix indicates the TSSOP16 plastic thin shrink small outline package, providing a compact solution for surface mount applications.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Direct substitutes within the same family include the 74HC138D (SO16 package) and 74HC138BQ (DHVQFN16 package). Verify pin compatibility and package dimensions when considering these alternatives for board layout changes.
