PA4684
Dual SPDT Analog Switch
Description
ProTek Analogâs PA4684 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 PA4684 has a maximum On-Resistance of 0.5â¦
at +2.7V.
Break-before-make switching prevents both switches being
enabled simultaneously. This eliminates signal disruption
during switching.
The control input, INX, tolerates input drive signals up to
6.0V, independent of supply voltage.
