Description
The BL4684C is a Dual Wide-Bandwidth, fast single-
pole double-throw (SPDT) CMOS switch featuring an
On-Resistance of 0.4 ohm at VDD=2.7V and wide
power supply range from 1.65V to5.5V. It can be
used as an analog switch or as a low-delay bus
switch.
Break-before-make function for both parts eliminates
signal disruption during switching from preventing
both switches being enabled simultaneously.
