Description
The PI3A4624 is a single-pole, double-throw (SPDT) analog switch.
Specifications include a low ON-Resistance of 0.4Ω, and fast
switching times (40ns Max.) with 3.0V supply operation.
Specifications are given for 1.8V, 2.5V and 3.3V power supply
operation. Operating voltage range is +1.5V to +3.6V.
To minimize PC board area use, the device is available in the ultra
compact TDFN, and the small compact SOT-23, 6-pin packages.
Operating temperature range is – 40°C to 85°C.
