BCT4223
Low-Voltage, 0.4Dual-SPDT Analog Switch
General Description
The BCT4223 is a high-performance, dual
single-pole double-throw (SPDT) analog switch.
Specified over a wide operating power supply voltage
range, 1.65V to 4.3V, Targeted applications include
battery powered equipment that benefit from ultra low
ON-resistance(0.4) and fast switching speeds.
Break-before-make switching prevents both switches
being enabled simultaneously. This eliminates signal
disruption during switching.
Applications
Cell Phones
PDAs
Portable Instrumentation
Battery Powered Communications
Computer Peripherals
