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)
