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 is LOW, all outputs are enabled; if STROBE
is HIGH, all outputs are LOW.
