Overview

32-Channel Vacuum-Fluorescent Display Driver HV518 Features ► 32 output lines ► 90V output swing ► Active pull-down ► Latches on all outputs ► Up to 6.
0MHz @ VDD = 5.
0V ► -40°C to +85°C operation Applications ► Vacuum flourescent displays ► DC plasma displays General Description The HV518 is designed for vacuum fluorescent or DC plasma applications, where it can serve as a segment, digit or matrix display driver.
Each device has 32 outputs, 32 latches and a 32-bit cascadable shift register.
Serial data enters the shift register on the LOW-to-HIGH transition of the clock input.
With latch enable (LE) HIGH, parallel data is transferred to the output buffers through a 32-bit latch.
When LE is low the data is stored in the latch.
When STROBE (STR) is LOW, all outputs are enabled; if STROBE is HIGH, all outputs are LOW.

5V 1200mW Operating temperature -40°C to +85°C Storage temperature -65°C to +150°C Absolute Maximum Ratings are those values beyond which damage to the device may occur.
Functional operation under these conditions is not implied.
Continuous operation of the device at the absolute rating level may affect device reliability.
All voltages are referenced to GND.
Notes: 1.
Duty cycle is limited by the total power dissipated in the package.
2.
For operation above 25OC ambient, derate linearly to 85OC at 20mW/OC.
