Product Summary

The HV5812PJ is a 20-channel serial input vacuum fluorescent display driver. It combines a 20-bit CMOS shift register, data latches, and control circuitry with high voltage MOSFET outputs. The HV5812PJ is primarily designed for vacuum-fluorescent displays. The CMOS shift register and latches allow direct interfacing with microprocessor-based systems. Data input rates are typically over 5.0MHz with 5V logic supply. Especially useful for inter-digit blanking, the BLANKING input of the HV5812PJ disables the output source drives and turns on the sink drivers. Use with TTL may require external pull-up resistors to ensure an input logic high.
