Description
AI
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.
