2.7ΩLow Voltage SPDT Analog Switch in 6-pin SOT363

LR1551

Description

Features

The LR1551 is a Single Wide-Bandwidth, fast single-

pole double-throw (SPDT) CMOS switch featuring an

On-Resistance of 2.7 ohm at V_CC=5.0V and wide

power supply range from 1.8V to 5.5V. It can be used

as an analog switch or as a low-delay bus switch.

The 300MHz high bandwidth performance supports

the high frequency application.

ꢀ

Wide Power Supply Range: 1.8V to 5.5V

High Bandwidth: 300MHz

High Off-Isolation:

84dB at 1MHz

51dB at 10MHz

ꢀ

On-Resistance: 2.7Ω(typ) at 5.0V

Fast Switching Time

Break-before-make function for both parts eliminates

signal disruption during switching from preventing

both switches being enabled simultaneously.

t_on= 12.0ns; t_off= 5.0ns
