8-Bit µp-compatible D/A converter  
NE/SE5018/5019  
DESCRIPTION  
PIN CONFIGURATIONS  
The NE/SE5018/19 is a complete 8-bit digital-to-analog converter  
subsystem on one monolithic chip. The data inputs have input  
latches which are controlled by a latch enable pin. The data and  
latch enable inputs are ultra-low loading for easy interfacing with all  
logic systems. The latches appear transparent when the LE input is  
in the low state. When LE goes high, the input data present at the  
moment of transition is latched and retained until LE again goes low.  
This feature allows easy compatibility with most microprocessors.

The chip also comprises a stable voltage reference (5V nominal)  
and high slew rate buffer amplifier. The voltage reference may be  
externally trimmed with a potentiometer for easy adjustment of  
full-scale while maintaining a low temperature coefficient.
