MC14051BCPG

Analog Switches, Multiplexers, Demultiplexers Overview

The MC14051BCPG is a digitally controlled analog multiplexer implementing an SP8T solid-state switch in a PDIP-16 package. It operates on a single supply voltage ranging from 3.0 V to 18 V, with the analog signal range spanning the full VDD to VEE difference. The device features low ON impedance and very low OFF leakage current, ensuring effective signal isolation. Key electrical parameters include a maximum ON resistance of 1050 Ohms at 3V and 280 Ohms at 15V, a bandwidth of 17 MHz, and propagation delays up to 90 ns. It supports through-hole mounting and functions as a break-before-make switch.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the ordering suffix 'G' confirms Pb-Free compliance per the manufacturer's documentation. Confirm the package type is PDIP-16 for through-hole implementation. Check the specific revision status of the datasheet to ensure alignment with current manufacturing specifications. Ensure compatibility with standard CMOS logic levels for control inputs.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when an 8-channel analog multiplexer is required within a 16-pin footprint. Verify that the supply voltage range of 3V to 18V matches the system design. Consider the ON resistance values relative to the load requirements. Ensure the operating temperature range of -55°C to +125°C meets environmental constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MC1405xB family of analog multiplexers, which also includes the dual 4-channel MC14052B and triple 2-channel MC14053B. All three devices share identical pinouts and functional characteristics, differing only in the number of channels provided. This allows for flexible design scaling while maintaining board layout consistency across similar product lines.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet explicitly lists CD4051 as a pin-for-pin replacement. Other compatible variants include HC4051 for lower ON resistance applications. Verify that any substitute maintains the same PDIP-16 package and voltage specifications.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the maximum analog voltage swing allowed?

The analog voltage range is determined by the difference between VDD and VEE, supporting a total span of 3.0 V to 18 V.

How does the device handle control input signals?

Control inputs (A, B, C) are referenced to VSS and feature triple diode protection against high static voltages or electric fields.

Is the switching action simultaneous or sequential?

The switch function is designed as break-before-make, ensuring that the old connection is断开 before the new one is established.
