STMicroelectronics AS21P2TLR Analog Switch

STMicroelectronics AS21P2TLR Analog Switch is a high-speed CMOS single-pole double-throw (SPDT) analog switch or dual 2:1 multiplexer/demultiplexer bus switch. The AS21P2TLR is fabricated using silicon gate C2MOS technology. Designed to operate from 1.65V to 4.3V, this device is ideal for portable applications. It offers very low ON resistance (RON< 0.5 Ω) at VCC= 3.6 V. The nIN inputs are provided to control the independent channel switches nS1 and nS2. The switches nS1 are ON (connected to common ports Dn) when the nIN input is held high and OFF (state of high impedance exists between the two ports) when nIN is held low. The switches nS2 are ON (connected to common ports Dn) when the nIN input is held low and OFF (state of high impedance exists between the two ports) when IN is held high. Additional key features are fast switching speed, break-before-make delay time and ultralow power consumption. 

All inputs and outputs of the AS21P2TLR are equipped with protection circuits against static discharge, giving the device immunity from electrostatic discharge (ESD) and transient excess voltage.

The STMicroelectronics AS21P2TLR Analog Switch is offered in a compact 1.8mm x 1.4mm QFN10L package, ideal for space-constrained applications.
