UPD16326A

DATA SHEET MOS INTEGRATED CIRCUIT µPD16326A 32-BIT FLUORESCENT DISPLAY TUBE DRIVER The µPD16326A is a fluorescent display tube driver using a high breakdown voltage CMOS process. It consists of 32-bit bidirectional shift registers, a latch circuit, and a high breakdown voltage CMOS driver block. The logic block operates on a 5 V power supply designed to be connected directly to a microcontroller (CMOS level input). The driver block has a 150 V and 20 mA high breakdown voltage output, and both the logic block and driver block consist of CMOS, allowing operation with low power consumption. FEATURES High breakdown voltage CMOS structure High breakdown voltage, high current output (150 V, 20 mA) 32-bit bidirectional shift registers on chip Data control by transfer clock (external) and latch High-speed data transfer capability (fmax = 8.0 MHz MIN) Wide operating temperature range (TA = –40 to 85 ˚C) ORDERING INFORMATION Part Number Package 44-pin plastic QFP (4-direction leads) µPD16326AGB-3B4 Document No. S11760EJ1V0DS00 (1st edition) Date Published December 1997 N Printed in Japan © 1997 µPD16326A BLOCK DIAGRAM CLK A R/L 32-bit bidirectional shift registers B STB BLK 32-bit latch O1 O2 O32 PIN CONFIGURATION (Top View) O10 35 44 43 42 41 40 39 38 37 36 VDD2 VSS2 A BLK STB CLK VSS1 R/L VDD1 B VSS2 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 34 O11 O1 O2 O3 O4 O5 O6 O7 O8 O9 33 32 31 30 29 28 27 26 25 24 23 O12 O13 ...
