Description
Pericom Semiconductor's PI5A4684 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. Specified
over a wide operating power supply voltage, 1.65V to 5.5V, the
PI5A4684 has a maximum On-Resistance of 0.5Ω at +2.7V.
Break-before-make switching prevents both switches being
enabled simultaneously. This eliminates signal disruption during
switching.
The control input, IN
X
, tolerates input drive signals up to 6.0V,
independent of supply voltage.
