The MC14551B is a digitally–controlled analog switch. This device implements a 4PDT solid state switch with low ON impedance and very low OFF Leakage current. Control of analog signals up to the complete supply voltage range can be achieved.

• Triple Diode Protection on All Control Inputs
• Supply Voltage Range = 3.0 Vdc to 18 Vdc
• Analog Voltage Range (VDD – VEE) = 3.0 to 18 V Note: VEE must be
VSS
• Linearized Transfer Characteristics
• Low Noise — 12 nV√Cycle, f ≥ 1.0 kHz typical
• For Low RON, Use The HC4051, HC4052, or HC4053 High–Speed CMOS Devices
• Switch Function is Break Before Make
