MC14551B
Quad 2-Channel Analog
Multiplexer/Demultiplexer
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.

Plastic “P and D/DW” Packages: – 7.0 mW/_C From 65_C To 125_C
This device contains protection circuitry to guard against damage due to high
static voltages or electric fields. However, precautions must be taken to avoid
applications of any voltage higher than maximum rated voltages to this
