CD4555BPW

Signal Switches, Multiplexers, Decoders Overview

The CD4555BPW is a CMOS dual binary-to-1-of-4 decoder/demultiplexer from the Texas Instruments 4500B logic series. It integrates two independent decoders within a single 16-pin TSSOP package. The device operates on a supply voltage range of 3 V to 18 V and supports an operating temperature range from -55 °C to +125 °C. Key electrical parameters include a propagation delay of 190 ns, with each circuit featuring one input line and four output lines.

Signal Switches, Multiplexers, Decoders Feature Summary

• Dual architecture containing two independent binary-to-1-of-4 decoding circuits in a compact surface-mount package.

Signal Switches, Multiplexers, Decoders Applications

• Digital signal routing and demultiplexing applications
• Address decoding for memory or peripheral selection
• Industrial control systems requiring wide temperature operation

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific suffix 'PW' confirms the TSSOP-16 package type during procurement. Confirm RoHS compliance status via the manufacturer's official documentation, as environmental declarations may vary by production batch. Ensure the ordering quantity aligns with the reel packaging specifications provided by the distributor.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when dual independent decoding channels are required in a space-constrained design. The TSSOP-16 package offers a smaller footprint compared to traditional DIP options while maintaining standard pin compatibility. Verify that the 3 V to 18 V supply range meets the system power requirements and that the 190 ns propagation delay satisfies the timing constraints of the target application.
