The BL1555 is a Dual Wide-Bandwidth, fast single-pole double-throw (SPDT) CMOS switch featuring an On-Resistance of 0.3 ohm at VDD=5V and wide power supply range from 1.65V to 5.5V. 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.

• Wide Power Supply Range:1.65V to 5.5V
• Low On-Resistance:
• RON(NC) = 0.3Ω(VCC=5V)
• RON(NO) = 0.3Ω(VCC=5V)
• Low On-Resistance Flatness:
• RFLAT(NC) = 0.08Ω(VCC=5V)
• 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%
