STMicroelectronics AS21P2THB
The AS21P2THB is a high-speed CMOS low voltage dual analog SPDT (single pole double throw) switch or 2:1 multiplexer/demultiplexer switch fabricated in silicon gate C²MOS technology. It is designed to operate from 1.65 V to 4.3 V, thus making this device the ideal selection for portable applications. The SEL input is provided to control the switch.| Part No. | AS21P2THB |

APPLICATIONS
● Wearable t(s) QFN10 c (1.8 x 1.4 mm) ProduFEATURES
te● Ultra low power dissipation: ole – ICC = 1 A (max.) at TA = 85 °C s
● Low “ON” resistance: b – RON = 4.8 (TA = 25 °C) at VCC = 4.3 V - O – RON = 5.9 (TA = 25 °C) at VCC = 3.0 V )
● Wide operating voltage range: t(s – VCC (opr.) = 1.65 V to 4.3 V c
● 4.3 V tolerant and 1.8 V compatible threshold du on digital control input at VCC = 2.3 V to 3.0 V ro
● Typical bandwidth (-3 dB) at 800 MHz on all P channels te
● USB (2.0) high speed (480 Mbps) signal le switching compliant o
● Integrated fail safe function bs
● Interrupt function to indicate to the processor O that the device is in dedicated port charging
● Sport and fitness
● Portable equipment
DESCRIPTION
The SEL input is provided to control the switch. The switch nS1 is ON (connected to common ports Dn) when the SEL input is held high and OFF (high impedance state exists between the two ports) when SEL is held low, the switch nS2 is ON (it is connected to common port Dn) when the SEL input is held low and OFF (high impedance state exists between the two ports) when SEL is held high.
