BL1555MM

BL1555 Ultra Low ON-Resistance, Low Voltage, Dual, SPDT Analog Switch Features Description ⚫ Wide Power Supply Range:1.65V to 5.5V The BL1555 is a Dual Wide-Bandwidth, fast single- ⚫ Low On-Resistance: pole double-throw (SPDT) CMOS switch featuring an RON(NC) = 0.3Ω(VCC=5V) On-Resistance of 0.3 ohm at VDD=5V and wide power RON(NO) = 0.3Ω(VCC=5V) supply range from 1.65V to 5.5V. It can be used as Low On-Resistance Flatness: an analog switch or as a low-delay bus switch. ⚫ Break-before-make function for both parts eliminates RFLAT(NC) = 0.08Ω(VCC=5V) signal disruption during switching from preventing RFLAT(NO) = 0.08Ω(VCC=5V) ⚫ -3dB Bandwidth: 33MHz ⚫ Rail-to-Rail Signal Range ⚫ High Off-Isolation: -66dB (f=100 kHz) ⚫ Crosstalk Rejection: -74dB ⚫ Low Total Harmonic Distortion: 0.035% ⚫ Available in MSOP10 package both switches being enabled simultaneously.
