This document is the SCHS122I datasheet, which introduces the features and characteristics of the product, including wide voltage range, low on resistance, low crosstalk, fast switching speed and propagation speed, break-before-make switching, wide operating temperature range, high noise immunity, etc.
The CD54/74HC series are high‑speed CMOS analog multiplexers/demultiplexers that provide wide analog input voltage range, low on‑resistance, and fast switching. They operate from –55 °C to 125 °C and support supply voltages from 2 V to 6 V (HC types) or 4.5 V to 5.5 V (HCT types). Each device includes an enable pin that can disable all switches.
The datasheet lists ordering information for multiple package options (16‑lead CERDIP, PDIP, SOIC, SOP, TSSOP) and provides absolute maximum ratings, recommended operating conditions, and detailed DC electrical specifications such as on‑resistance, leakage currents, and input voltage thresholds.
