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)
