MC14066BDTR2G

Overview

The MC14066BDTR2G is a quad bilateral FET switch manufactured by onsemi, belonging to the MC14066B series. It features four independent SPST channels in a 14-TSSOP surface-mount package. The device operates on a single supply voltage ranging from 3 V to 18 V and supports dual supply configurations. Key electrical parameters include a maximum on-resistance of 280 Ohms, a maximum power dissipation of 500 mW, and a maximum supply current of 1 uA. It functions within an extended temperature range of -55°C to +125°C and meets AEC-Q100 automotive qualification standards.

Feature Summary

• Quad configuration providing four independent bilateral analog switches for signal routing
• CMOS technology enabling low static power consumption and high noise immunity
• Automotive grade qualification ensuring reliability under harsh environmental conditions
• Wide operating voltage range supporting diverse single and dual supply applications

Applications

• Automotive sensor signal conditioning and multiplexing

Procurement Notes

Verify the specific suffix BDTR2G confirms the TSSOP-14 package and tape-and-reel orientation. Confirm AEC-Q100 compliance requirements match the target application's quality standards. Ensure the 280 Ohm on-resistance specification aligns with the circuit's signal integrity needs. Check RoHS and REACH declarations against regional regulatory constraints. Validate that the 500 mW power dissipation rating accommodates the thermal design of the final assembly.

Selection Notes

Select this component when a quad analog switch with automotive qualification is required. The TSSOP-14 package offers a compact footprint suitable for space-constrained designs. The wide voltage range allows compatibility with various logic levels and power rails. Consider the on-resistance value when designing for low-voltage signal transmission. Verify that the operating temperature range covers the intended environmental exposure.

Part Context

This part belongs to the MC14066B family of quad bilateral switches. It serves as a surface-mount alternative to through-hole variants like the MC14066BDR2G, which uses a SOIC-14 package. The device integrates four independent switches into a single CMOS IC, replacing discrete transistor solutions. It is designed for general-purpose analog signal switching in digital and mixed-signal circuits.
