HI-8020 Series September 1999 GENERAL DESCRIPTION The HI-8020 high voltage display driver is a functional replacement for the AMI S5420 and Micrel MIC8013/8014 series. This CMOS product is designed to drive liquid crystal displays by converting 5 volt serial data to parallel segment and backplane waveforms with amplitudes up to 30 volts. The HI-8020 differs from the HI-8010 by only the shift register clock logic gating with chip select. The chip can drive up to 38 segments and has 4 possible shift register data taps to provide options to cascade devices for larger displays. Data is clocked into a 38 stage shift register and parallel latched before the output translators by a Load input. The HI-8020 is available in a variety of ceramic and plastic packaging including DIP; leaded and leadless chip carriers; and J-lead and gull-wing quad flat packs.

NEW) HOLT INTEGRATED CIRCUITS 3-9 SEGMENTS 9/99 HI-8020 Series INTERNAL OSCILLATOR CIRCUIT FUNCTIONAL DESCRIPTION Whenever a Logic "0" is applied to the Chip Select (CS) input, one bit of data is clocked into the shift register with each negative transition of the Clock (CL) input. CS is internally tied to VSS on some versions. A Logic "1" present at the Load (LD) input will cause a parallel transfer of data from the shift register to the data latch. If the Load (LD) input is held high while data is clocked into the shift register, the latch will be transparent. C To display segments, a Logic "1" is stored in the appropriate shift register bit position, and the segment output is out-ofphase with the backplane. The backplane output functions in 1 of 2 modes; externally driven or self-oscillating. When the LCDØ input is externally driven with the LCDØ OPT input open circuit (Figure 2), the backplane output will be in-phase with LCDØ. Utilizing the self-oscillating mode, inputs LCDØ and LCDØ OPT are tied together and connected to an RC circuit (Figure 3). A 150KW resistor with a 470pF capacitor generates an approximate backplane frequency of 100Hz. The LCDØ/LCDØ OPT oscillator frequency is divided by 256 to determine the backplane output frequency. R ÷ 256 Q LCDØ LCDØ OPT TO BACKPLANE TRANSLATOR AND DRIVER For displays having a number of segments greater that 38, two or more of the display drivers may be cascaded together by connecting the serial data output (DOUT) from the first driver, to the serial data input (DIN) of the following driver, etc. Data out (DOUT) will change state on the rising edge of the Clock (CL). Clock (CL), Load (LD) and Chip Select (CS) should be tied in common with each other, respectively, between all cascaded display drivers. Figure 1.
