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.
