Digital-to-Analog Converters with Serial Interface

CMOS LSI

The MC144110 and MC144111 are low±cost 6±bit D/A converters with serial interface ports to provide communication with CMOS microprocessors and microcomputers. The MC144110 contains six static D/A converters; the MC144111 contains four converters.

Due to a unique feature of these DACs, the user is permitted easy scaling of the analog outputs of a system. Over a 5 to 15 V supply range, these DACs may be directly interfaced to CMOS MPUs operating at 5 V.

•Direct R±2R Network Outputs

•Buffered Emitter±Follower Outputs

•Serial Data Input

•Digital Data Output Facilitates Cascading

•Direct Interface to CMOS μP

•Wide Operating Voltage Range: 4.5 to 15 V

•Wide Operating Temperature Range: 0 to 85°C

•Software Information is Contained in Document M68HC11RM/AD

* Maximum Ratings are those values beyond which damage to the device may occur.

This device contains protection circuitry to guard against damage due to high static voltages or electric fields; however, it is advised that precautions be taken to avoid application of voltage higher than maximum rated voltages to this high±impedance circuit. For proper operation it is recommended that Vin and Vout be constrained to the range VSS ≤

(Vin or Vout) ≤VDD.

Unused inputs must always be tied to an appropriate logic voltage level (e.g., either VSS or VDD).
