NTE2031
Integrated Circuit
SevenSegment GasDischarge Display Driver
Description:
The NTE2031 is a seven channel digit (anode) driver in a 16Lead DIP type package specifically de-
signed to be used with highvoltage, gasdischarge numeric displays. This device requires a low
logic level to turn the drivers on with a low input current requirement of any 300
A typically, and is
compatible with popular MOS chips.
