74AC253PC

Signal Switches, Multiplexers, Decoders Overview

The Fairchild Semiconductor 74AC253PC is a dual 4-input multiplexer featuring 3-STATE outputs, housed in a 16-pin Plastic Dual-In-Line (PDIP) package. It operates within a supply voltage range of 2 V to 6 V and supports through-hole mounting. The device provides two independent circuits capable of selecting data from four sources using common select inputs. Propagation delay is specified at 14.5 ns at 3.3 V and 10 ns at 5 V. It functions reliably across an operating temperature range of -40°C to +85°C.
