Vishay DG9232DY-T1-E3 Low-voltage dual spst analog switch Datasheet

DG9232/9233
Vishay Siliconix
Low-Voltage Dual SPST Analog Switch
DESCRIPTION
FEATURES
The DG9232/9233 is a single-pole/single-throw monolithic
CMOS analog device designed for high performance
switching of analog signals. Combining low power, high
speed (tON: 35 ns, tOFF: 20 ns), low on-resistance (rDS(on):
20 Ω) and small physical size, the DG9232/9233 is ideal for
portable and battery powered applications requiring high
performance and efficient use of board space.
The DG9232/9233 is built on Vishay Siliconix’s low voltage
BCD-15 process. Minimum ESD protection, per Method
3015.7 is 2000 V. An epitaxial layer prevents latchup.
Break-before -make is guaranteed for DG9232/9233.
