About this manual

The CD54/74HC4051‑4053 and CD74HCT4051‑4053 devices are digitally controlled analog switches built with silicon‑gate CMOS technology. They provide bidirectional switching, allowing any analog input to be used as an output and vice‑versa, and feature an enable pin that can disable all channels.

Key features include a wide analog input voltage range (up to 10 V), low on‑resistance (typical 70 Ω at 4.5 V), low crosstalk, fast switching, and operation over a temperature range of –55 °C to 125 °C. The datasheet lists detailed electrical specifications, pin‑out diagrams, package options (CERDIP, PDIP, SOIC, SOP, TSSOP), and ordering information.
