MC14066BDG

Overview

The MC14066BDG is a quad analog switch manufactured by onsemi, housed in a 14-lead SOIC package. It features four independent bilateral switches capable of controlling digital or analog signals with input voltage swings up to the full supply voltage. The device operates within a power supply range of 3 V to 18 V and supports a maximum operating temperature of +125 °C. Key electrical parameters include a maximum on-resistance of 280 Ohms, a bandwidth of 65 MHz, and a maximum propagation delay of 120 ns. The component dissipates up to 500 mW and is designed for pin-for-pin compatibility with similar legacy devices.

Feature Summary

• Provides four independent bilateral switches for signal gating and modulation
• Features linearized transmission characteristics for accurate analog signal handling
• Includes triple diode protection on all control inputs for enhanced reliability

Applications

• Signal processing circuits
• Communication and network systems
• Chopper and modulator implementations

Procurement Notes

Verify the specific suffix 'DG' against the manufacturer's current datasheet to confirm the exact tape-and-reel or tube packaging configuration intended for procurement. Ensure that the ordering information matches the required lead-free status and RoHS compliance specifications as defined in the official product documentation before finalizing purchase orders.

Selection Notes

Select this component when a quad analog switch with low on-resistance is required for CMOS logic implementation or signal separation. It serves as a direct replacement for the MC14016B where lower resistance is beneficial. Consider the 3 V to 18 V supply range and -55 °C to +125 °C operating temperature window to ensure suitability for the target environmental conditions.

Part Context

This part belongs to the MC14066B series of analog multiplexers and switches from onsemi. It is designed to be pin-compatible with the MC14016B but offers significantly lower on-resistance. The series is categorized under standard product analog switches, suitable for general-purpose signal routing in mixed-signal applications.

Replacement Considerations

The MC14066B is designed to be pin-for-pin compatible with the MC14016B. Verify that the lower on-resistance of the MC14066B does not impact existing circuit biasing when substituting.
