NTE4051B & NTE4051BT
Integrated Circuit
CMOS, Analog, Single 8−Channel
Multiplexer/Demultiplexer
Description:
The NTE4051B (16−Lead DIP) and NTE4051BT (SOIC−16) analog multiplexers are digitally−
controlled analog switches. These devices effectively implement an SP8T solid state switch and
feature low ON impedance and very low OFF leakage current. Control of analog signals up to the
complete supply voltage range can be achieved.

Note 1. 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.
Note 2. These devices contain 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, Vin and Vout should be constrained to the range VSS ≤ (Vin or Vout) ≤ VDD.
Unused inputs must always be tied to an appropriate logic voltage level (e.g. eiher VSS, VEE
or VDD), Unused outputs must be left open.

Note 3. Data labeled “Typ” is not to be used for design purposes but is intended as an indication of
the device’s potential performance.
Note 4. For voltage drops across the switch (ΔVswitch) > 600mV (> 300mV at high temperatures),
excessive VDD current may be drawn, i.e. the current out of the switch may contain both VDD
and switch input components. The reliability of the device will be unaffected unless the Maximum Ratings are exceeded (See the first page of this data sheet).
