| HV7620 40MHz, 32-Channel Serial to Parallel Converter with Push-Pull Outputs Ordering Information Package Options Device HV76 64 Pin Plastic Gullwing HV7620PG 80-Lead Ceramic Gullwing HV7620DG Die in Wafer Form HV7620XW Features Processed with HVCMOS(R) technology 5V CMOS logic and 12V supply rail Output voltage up to 200V Low power level shifting Source/sink current minimum 50mA 40MHz equivalent data rate Chip select Polarity function Forward and reverse shifting options (DIR pin) Latched outputs General Description The HV76 is a low-voltage serial to high-voltage parallel converter with push-pull outputs. This device has been designed for use as a driver for color AC plasma displays. The device has 4 parallel 8-bit shift registers permitting data rate 4 times the speed of one. The data are clocked in simultaneously on all four data inputs with a single clock. Data are shifted in on a low to high transition of the clock. The latches and control logic perform the output enable function. The DIR pin causes clockwise (CW) shifting of the data when connected to VDD1, and counterclockwise (CCW) shifting when connected to GND. Operation of the shift register is not affected by the LE (latch enable) input. Transfer of data from the shift registers to the latches occurs when the LE input is high. Data is stored in the latches when LE is low. The current source on the logic inputs provides active pull up when the input pins are open. Absolute Maximum Ratings Supply voltage1, VDD1 Supply voltage , VDD2 Supply voltage1, VPP Logic input levels1 Continuous total power dissipation Operating temperature range Storage temperature range Notes: 1. All voltages are referenced to GND. 2. For operation above 25C ambient derate linearly to maximum operating temperature at 20mW/C for plastic and at 19mW/C for ceramic. 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."
