Description

The LR1552 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.
