DG191AP/B

Analog Switches, Multiplexers, Demultiplexers Overview

The DG191AP/B is a dual single-pole double-throw (SPDT) analog switch manufactured by Rochester Electronics. It operates with a maximum supply voltage of ±15 V and supports signal voltages up to ±12 V. The device features a low on-resistance of 150 Ω and an off-isolation of 60 dB at 1 MHz. It includes a built-in clamp diode for input protection and offers a propagation delay of 300 ns. The component is housed in a 16-pin ceramic DIP package and functions within a temperature range of -55 °C to 125 °C.
