CD4556BE

Signal Switches, Multiplexers, Decoders Overview

The CD4556BE is a dual binary-to-1-of-4 decoder/demultiplexer from the Texas Instruments 4000B series. It integrates two independent circuits within a single 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, high-level output current of 6.8 mA, and low-level output current of 6.8 mA. It functions with inverted outputs that are low on select and is rated for an operating temperature range of -55°C to +125°C.
