DESCRIPTION PIN CONFIGURATIONS The NE/SE5018/19 is a complete 8-bit digital-to-analog converter
F, N Packages
subsystem on one monolithic chip. The data inputs have input
latches which are controlled by a latch enable pin. The data and DIGITAL GND ANALOG GND
latch enable inputs are ultra-low loading for easy interfacing with all DB0(LSB) AMP COMP logic systems. The latches appear transparent when the LE input is DB1 SUM MODE in the low state. When LE goes high, the input data present at the
DB2 VCC+
moment of transition is latched and retained until LE again goes low.
DB3 VOUT
This feature allows easy compatibility with most microprocessors.

The chip also comprises a stable voltage reference (5V nominal)
DB6 BIPOLAR
and high slew rate buffer amplifier. The voltage reference may be
