Supertex inc. HV5408B 32-Channel Serial to Parallel Converter With High Voltage Push-Pull Outputs Features ►► Processed with HVCMOS® technology ►► Low power level shifting ►► SOURCE/SINK current minimum 20mA ►► Shift register speed 8.0MHz ►► Latched data outputs ►► CMOS compatible inputs ►► Forward and reverse shifting options ►► Diode to VPP allows efficient power recovery General Description The HV5408B 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 AC-electroluminescent displays. It can also be used in any application requiring multiple output high voltage current sourcing and sinking capabilities, such as driving plasma panels, vacuum fluorescent, or large matrix LCD displays. The HV5408B consists of a 32-bit shift register, 32 latches, and 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. Typical Application Circuit VDD DATA INPUT CLK Low Voltage Micro Processor LE OE Shift Register Latches Output Contr.

Functional operation under these conditions is not implied. Continuous operation of the device at the absolute rating level may affect device reliability. All voltages are referenced to device ground. Notes: 1. Duty cycle is limited by the total power dissipated in the package. 2. For operation above 25°C ambient derate linearly to maximum operating temperature at 20mW/°C for plastic and at 15mW/°C for ceramic. 44-Lead PLCC .653x.653in body .180in height (max) .050in pitch HV5408PJ-B-G Pin Configurations 6 1 44 40 44-Lead Quad Cerpac (DJ) (top view) 44 1 44-Lead PQFP (PG) (top view) 6 1 44 40 44-Lead PLCC (PJ) (top view) Product Marking Top Marking YYWW HV5408DJ-B LLLLLLLLLL YY = Year Sealed WW = Week Sealed L = Lot Number Bottom Marking C = Country of Origin* CCCCCCCCCCC AAA A = Assembler ID* *May be part of top marking 44-Lead Quad Cerpac (DJ) Top Marking YYWW HV5408PG-B LLLLLLLLL Bottom Marking CCCCCCCC AAA YY = Year Sealed WW = Week Sealed L = Lot Number C = Country of Origin* A = Assembler ID* = “Green” Packaging *May be part of top marking 44-Lead PQFP (PG) Packages may or may not include the following marks: Si or Top Marking YY = Year Sealed YYWW AAA HV5408PJ-B WW = Week Sealed LLLLLLLLLL L = Lot Number Bottom Marking A C = = Assembler Country of ID Origin* = “Green” Packaging CCCCCCCCCCC *May be part of top marking 44-Lead PLCC (PJ) Supertex inc. ● 1235 Bordeaux Drive, Sunnyvale, CA 94089 ● Tel: 408-222-8888 ● www.supertex.com 2 HV5408B Recommended Operating Conditions (over -40°C to 85°C for plastic and -55°C to 125°C for ceramic) Sym Parameter Min Max Units VDD Logic voltage supply VPP High voltage supply VIH Input high voltage VIL Input low voltage fCLK Clock frequency 10.8 8.0 VDD - 2.0 0 0 13.2 80 VDD 2.0 8.0 V V V V MHz Power-Up Sequence Power-up sequence should be the following: 1.
