The PD16337 is a high-voltage CMOS driver designed for flat display panels such as PDPs, VFDs and ELs. It consists of a 64-bit bi-directional shift register (16 bit x 4 circuits), 64-bit latch and high-voltage CMOS driver. The logic block is designed to operate at 5-V power supply, enabling direct connection to a microcontroller. In addition, the PD16337 achieves low power dissipation by employing CMOS structure while having a high withstand voltage output (150 V, 40 mA MAX.)
