HEF4555BP,652

Signal Switches, Multiplexers, Decoders Overview

The HEF4555BP,652 is a dual 1-of-4 decoder/demultiplexer from the HE4000B CMOS logic family. It contains two independent decoders, each with two address inputs (nA0, nA1), an active LOW enable input (nE), and four mutually exclusive active HIGH outputs (nY0 to nY3). The device operates within a supply voltage range of 3 V to 15 V referenced to ground. It features high noise immunity, fully static operation, and standardized symmetrical output characteristics compliant with JEDEC JESD 13-B standards.
