| HV62208 32-Channel 256 Gray-Shade High Voltage Driver Ordering Information Package Option Device HV62208 64-Lead 3-Sided Plastic Gullwing HV62208PG Die HV62208X Features HVCMOS(R) technology 5V CMOS inputs Up to 80V output voltage PWM gray shade conversion Capable of 256 levels of gray shading Balanced shift clock complies with RS-422 8MHz shift and count clock frequency 16MHz data throughput rate 8 bit data bus 32 outputs per device BLANK function General Description Not recommended for new designs. Please use HV632 instead. The HV622 is a 32-channel gray-shade column driver IC designed for driving electrofluorescent displays. Using Supertex's unique HVCMOS(R) technology, it is capable of 256 levels of gray shading by PWM conversion. The shift clock is a balanced clock with electrical characteristics complying with EIA RS-422 standard. Input data, in groups of eight, is latched into a set of data latches on both edges of the shift clock. The data shifted in the first data latch corresponds to HVOUT1, the second data latch corresponds to HVOUT2, and so on. These data are compared to the contents of the master binary counter which counts on both edges of the count clock. Each time the master counter begins to decrement from 1111 1111, the data in the data latches are compared with the contents of the counter; if they match, the corresponding outputs will go high. The master counter counts down to 0000 0001 and then starts to count up again. The outputs that are at high will stay at high until the contents of the counter match the data in the data latches again. Therefore, the higher the binary data in the data latches, the longer the outputs will stay at high. Thus, different high voltage pulse widths are produced. When the counter reaches its 1111 1111 count while counting up, the device is ready for the next operation cycle. A data value of 0000 0000 produces no pulse; the output stays low. The BLANK input signal will reset the master counter to all ones (1111 1111) and set all high voltage outputs to low. Absolute Maximum Ratings Supply voltage, VDD Supply voltage, VPP Supply voltage, VNN Logic input levels Continuous total power dissipation Operating temperature range Storage temperature range -0.5V to +7.5V -0.5V to +80V -15V to 0V -0.5 to VDD + 0.5V 1.2W -40C to +85C -65C to +150C Notes: All voltages are referenced to GND. Maximum VPP to VNN voltage is 90V. For operation above 25C ambient derate linearly to 85C at 20mW/C. 02/96/022 Supertex Inc. does not recommend the use of its products in life support applications and will not knowingly sell its products for use in such applications unless it receives an adequate "products liability indemnification insurance agreement."
