CD4555BE

Signal Switches, Multiplexers, Decoders Overview

The CD4555BE is a dual binary 1-of-4 decoder/demultiplexer from the Texas Instruments 4500B logic series. It features two independent circuits, each with one input line and four output lines, housed in a 16-pin PDIP package. The device operates on a supply voltage range of 3 V to 18 V and supports through-hole mounting. Key electrical parameters include a propagation delay of 190 ns, a power dissipation of 500 mW, and an operating temperature range from -55 °C to +125 °C.

Signal Switches, Multiplexers, Decoders Feature Summary

• Dual circuit architecture providing two independent 1-to-4 decoding or demultiplexing functions within a single package.
• CMOS technology enabling operation across a wide supply voltage range from 3 V to 18 V.
• Industrial-grade thermal stability supporting reliable performance in extreme environments ranging from -55 °C to +125 °C.

Signal Switches, Multiplexers, Decoders Applications

• Address decoding for memory systems
• Data routing in digital communication interfaces
• Control signal distribution in industrial automation

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific suffix 'BE' corresponds to the PDIP-16 through-hole package variant when sourcing. Confirm RoHS compliance status via the manufacturer's official documentation, as environmental declarations may vary by production batch. Ensure the ordering part number matches the required lead time and factory packaging quantity specified in current distributor catalogs.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a design requires two separate 1-of-4 decoding paths in a standard DIP footprint. It serves as a direct replacement for legacy 4000-series CMOS decoders. Consider the 190 ns propagation delay and 500 mW power dissipation limits during thermal analysis. Verify that the 3 V to 18 V supply range aligns with the system's available voltage rails.

Signal Switches, Multiplexers, Decoders Part Context

This device belongs to the CD4555B family, which includes surface-mount variants such as the CD4555BMT. While functionally similar, the BE suffix specifically denotes the plastic dual-in-line package suitable for prototyping and high-reliability through-hole applications. It shares the 4500B logic series characteristics with other Texas Instruments CMOS devices.

Signal Switches, Multiplexers, Decoders Replacement Considerations

The CD4555BM96 is listed as a parameter-equivalent substitute. Verify pinout compatibility and package dimensions before substitution. Other family members like the CD4556BE offer different configuration options.
