Supertex inc. HV5408B 32-Channel Serial to Parallel Converter With High Voltage Push-Pull Outputs Features General Description Processed with HVCMOS technology The HV5408B is a low voltage serial to high voltage parallel converter with push-pull outputs. This device has been designed Low power level shifting for use as a driver for AC-electroluminescent displays. It can also SOURCE/SINK current minimum 20mA be used in any application requiring multiple output high voltage Shift register speed 8.0MHz current sourcing and sinking capabilities, such as driving plasma Latched data outputs panels, vacuum fluorescent, or large matrix LCD displays. CMOS compatible inputs Forward and reverse shifting options The HV5408B consists of a 32-bit shift register, 32 latches, and Diode to VPP allows efficient power recovery control logic to enable outputs. Q1 is connected to the first stage of the shift register through the Output Enable logic. Data is shifted through the shift register on the low to high transition of the clock. When viewed from the top of the package, the HV5408B shifts in the counter-clockwise direction. A data output buffer is provided for cascading devices. This output reflects the current status of the last bit of the shift register (32). Operation of the shift register is not affected by the LE (latch enable) or the OE (output enable) inputs. Transfer of data from the shift register to the latch occurs when the LE input is high. The data in the latch is retained when LE is low.

Functional operation under these conditions is not implied. (top view) Continuous operation of the device at the absolute rating level may affect device reliability. All voltages are referenced to device ground. 6 1 44 40 Notes: 1. Duty cycle is limited by the total power dissipated in the package. 2. For operation above 25C ambient derate linearly to maximum operating temperature at 20mW/C for plastic and at 15mW/C for ceramic. 44-Lead PLCC (PJ) (top view) Product Marking Top Marking Top Marking Top Marking YY = Year Sealed YYWW YYWW YY = Year Sealed YYWW AAA WW = Week Sealed YY = Year Sealed HV5408DJ-B HV5408PG-B HV5408PJ-B LLLLLLLLLL WW = Week Sealed LLLLLLLLL LLLLLLLLLL L = Lot Number WW = Week Sealed L = Lot Number A = Assembler ID L = Lot Number Bottom Marking Bottom Marking C = Country of Origin* Bottom Marking C = Country of Origin* C = Country of Origin* A = Assembler ID* = Green Packaging A = Assembler ID* CCCCCCCCCCC CCCCCCCCCCC CCCCCCCC = Green Packaging *May be part of top marking AAA *May be part of top marking AAA *May be part of top marking 44-Lead Quad Cerpac 44-Lead PQFP 44-Lead PLCC (DJ) (PG) (PJ) Packages may or may not include the following marks: Si or Supertex inc. 1235 Bordeaux Drive, Sunnyvale, CA 94089 Tel: 408-222-8888 www.supertex.com 2
