... Digital-to-Analog Converters with Serial Interface CMOS LSI 1 Introduction 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 ...

... Data is shifted into the register on the high-to-low transition of CLK. CLK is fed into the D-input of a transparent latch, which is used for inhibiting the clocking of the shift register when ENB is high. The number of clock cycles required for the MC144110 is usually 36. The MC144111 usually uses 24 cycles. See Table 4 for additional information. ...
