Low Voltage Dual SPDT 0.8Ω Analog Switch
Features
Description
The PI5A23159 is a dual high-bandwidth, fast single-
pole double-throw (SPDT) CMOS switch. It can be used
as an analog switch or as a low-delay bus switch. The
device features ultra low RON of 0.8Ω typical at 3.0V
VCC and will operate over the wide VCC range of
1.65V to 5.5V.
The PI5A23159 features very low quiescent current
even when the control voltage is lower than the VCC
supply. This feature services the mobile handset
applications very well by allowing direct interface with
baseband processor general purpose I/Os.
Break-before-make switching prevents both switches
being enabled simultaneously. This eliminates signal
disruption during switching.
The control input, S, is independent of supply voltage.
