Description
The PI3A412 is a quad single-pole double-throw (SPDT) CMOS
switch. It can be used as an analog switch or as a low-delay bus
switch. Specified over a wide operating power supply voltage
range, +1.6V to +4.2V, the switch has an On-Resistance of 0.4Ω
at 2.7V.
Control inputs, Ax, tolerates input drive signals up to 5V, indepen-
dent of supply voltage.

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 VCC = 4.2V unless otherwise specified.
3. Guaranteed by design.
4. Off Isolation = 20log10 [ (VNO or VNC) / VCOM ]. See Figure 5.
5. Between any two switches. See Figure 6.
