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.

Stresses exceeding Maximum Ratings may damage the device. Maximum
Ratings are stress ratings only. Functional operation above the Recommended
Operating Conditions is not implied. Extended exposure to stresses above the
Recommended Operating Conditions may affect device reliability.

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
high−impedance circuit. For proper operation, V and V should be constrained

to the range V v (V or V ) v V for control inputs and V ≤ (V or V
