SN2412
0.6Ω, 2.7V, Quad SPDT Analog Switch
General Description
Features
The SN2412 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 0.6Ω at 2.7V.

Note 1: Signals on NC, NO, COM, or A exceeding VCC or GND are clamped by internal diodes. Limit forward diode current to 30mA.
Caution: Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is
a stress only rating and operation of the device at these or any other conditions beyond those indicated in the operational
sections of this specification is not implied.

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 TA = 25°C, VCC = 4.2V unless otherwise specified.
3. Guaranteed by design.
4. ∆RON = RON match between channels
5. Flatness is defined as the difference between the maximum and minimum value of On-Resistance measured.
6. Leakage parameters are 100% tested at maximum rated hot temperature and guaranteed by correlation at +25ºC.
