SCHS122G is a digitally controlled analog switch developed by Harris Semiconductor. It uses silicon gate CMOS technology and operates in a similar way to LSTTL, with low power consumption. The switch voltage range is 0V to 10V, and the load voltage range is ±5V. It has low resistance, low crosstalk, and fast switching.
The CD54/74HC4051‑4053 family are high‑speed CMOS analog multiplexers/demultiplexers that use silicon‑gate technology to provide low on‑resistance, low crosstalk, and fast switching. They are bidirectional switches with an enable pin that can disable all channels.
Key features include a wide analog input voltage range (+5 V max), operation over –55 °C to 125 °C, supply voltage ranges of 2 V‑6 V (HC types) or 4.5 V‑5.5 V (HCT types), and various package options such as PDIP, SOIC, SOP, and TSSOP. Ordering information, pinouts, functional diagrams, and absolute maximum ratings are detailed throughout the document.
| On‑Resistance (Typical) | 70 Ω (Voc‑Veg = 4.5 V) |
|---|---|
| Operating Temperature Range | -55 °C to 125 °C |
| Operation Control Voltage (HC types) | 2 V to 6 V |
| Switch Voltage | 0 V to 10 V |
| Logic Compatibility (HCT types) | V_IL ≤ 0.8 V, V_IH ≥ 2 V |
They are rated for operation from –55 °C to 125 °C.
HC type parts require an operation control voltage between 2 V and 6 V.
