Leshan Radio Co ., Ltd 2.7Ω Ω Low Voltage SPDT Analog Switch in 6-pin SOT363 LR1551 Features Description Wide Power Supply Range: 1.8V to 5.5V The LR1551 is a Single Wide-Bandwidth, fast single- High Bandwidth: 300MHz pole double-throw (SPDT) CMOS switch featuring an High Off-Isolation: On-Resistance of 2.7 ohm at VCC=5.0V and wide 84dB at 1MHz power supply range from 1.8V to 5.5V. It can be used 51dB at 10MHz as an analog switch or as a low-delay bus switch. On-Resistance: 2.7Ω(typ) at 5.0V Fast Switching Time The 300MHz high bandwidth performance supports the high frequency application. Break-before-make function for both parts eliminates ton = 12.0ns; toff = 5.0ns signal disruption during switching from preventing TTL/CMOS Compatible Break-Before-Make Switching Rail-to-Rail Signal Range Operation Temperature Range: both switches being enabled simultaneously.
