AS1742G

Analog Switches, Multiplexers, Demultiplexers Overview

The AS1742G is a high-speed, low-voltage analog switch featuring dual single-pole/single-throw (SPST) normally closed channels. It operates on a single supply voltage ranging from +1.6V to +3.6V. The device provides an ON-resistance of 0.8Ω at +3V and 2.5Ω at +1.8V, with RON matching of 0.08Ω and flatness of 0.18Ω. Switching times are tON = 22ns and tOFF = 14ns at +3V. It handles continuous currents up to 250mA and supports rail-to-rail signal switching. Logic inputs are compatible with 1.8V CMOS when using a +3V supply. Available in 8-pin MSOP and SOT23 packages.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific package variant required for the design, as the AS1742G designation typically refers to the tube-packaged 8-pin MSOP version. Confirm availability status directly with the manufacturer or authorized distributors, as component lifecycle stages can change without immediate public notice. Ensure ordering suffixes match the desired delivery form, such as tape and reel options if available.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the AS1742G when normally closed signal paths are required in low-voltage applications. Compare against the AS1741 for normally open configurations. Consider the AS1743 if break-before-make switching functionality is needed. Verify that the operating voltage range aligns with the system's power supply constraints and that the logic input levels remain compatible with the control interface.

Analog Switches, Multiplexers, Demultiplexers Part Context

The AS1742G belongs to the AS1741/AS1742/AS1743 family of high-speed analog switches manufactured by ams OSRAM. These devices share identical electrical characteristics and pinouts but differ in their internal switch configuration. The AS1742 specifically utilizes two normally closed contacts, distinguishing it from the normally open AS1741 and the mixed NO/NC AS1743 within the same product line.
