Description
The PI3A4624 is a single-pole, double-throw (SPDT) analog switch.
Specifications include a low ON-Resistance of 0.4, 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 40C to 85C.

Notes:
1. The algebraic convention, where most negative value is a minimum and most positive is a maximum, is used in this data sheet.
2. Typical values are for DESIGN AID ONLY, not guaranteed or subject to production testing.
3. Guaranteed by design.
