MC144111DWR2

Digital To Analog Converters Overview

The MC144111DWR2 is a low-cost CMOS LSI digital-to-analog converter (DAC) containing four independent 6-bit static channels. It features a serial interface for communication with microprocessors and supports direct interfacing to 5V CMOS logic over a wide supply voltage range of 4.5 V to 15 V. The device provides both buffered emitter-follower outputs and direct R-2R resistor network outputs, allowing flexible scaling of analog signals. It operates within a temperature range of 0°C to 85°C.

Digital To Analog Converters Feature Summary

• Four-channel architecture with serial data input and cascading capability via digital output
• Dual-output configuration offering buffered emitter-follower and unbuffered R-2R resistor network terminals
• Wide operating voltage range enabling direct interface to 5V microprocessors without level shifting
• Integrated transparent latch and shift register for simplified software control

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel analog signal generation
• Portable instrumentation powered by single-supply batteries
• Embedded systems utilizing CMOS microcontrollers for DAC expansion
• Audio and signal processing circuits requiring programmable gain or offset adjustment

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix 'DW' corresponds to the SOG package (Case 751G) as defined in the datasheet. Confirm that the 'R2' designation aligns with manufacturer reel packaging specifications. Ensure compatibility with the required 16-pin surface-mount footprint during PCB layout verification.

Digital To Analog Converters Selection Notes

Select this component when four independent 6-bit DAC channels are required in a compact surface-mount package. Compare against the MC144110 if six channels are needed instead of four. Consider the MC144111P variant if through-hole plastic DIP packaging is preferred for prototyping or specific mechanical constraints.

Digital To Analog Converters Part Context

The MC144111DWR2 belongs to the MC14411x family of CMOS digital-to-analog converters manufactured by Freescale Semiconductor (now NXP). This series is designed for cost-sensitive applications requiring multiple DAC channels with simple serial control interfaces. The DW suffix specifically denotes the SOG surface-mount package option within this product line.

Digital To Analog Converters Replacement Considerations

The MC144111DW serves as the direct pin-compatible alternative in the same package type. For through-hole requirements, the MC144111P offers identical electrical functionality in a Plastic DIP package. Verify pinout compatibility before substituting any other quad-channel DAC devices.
