NTE NTE2031

NTE2031
Integrated Circuit
Seven–Segment Gas–Discharge Display Driver
Description:
The NTE2031 is a seven channel digit (anode) driver in a 16–Lead DIP type package specifically designed to be used with high–voltage, gas–discharge numeric displays. This device requires a low
logic level to turn the drivers on with a low input current requirement of any 300µA typically, and is
compatible with popular MOS chips.
Features:
D High Breakdown Voltage: –55V Typ
D Low Input Current for MOS Compatibility
D Operable from Either Positive or Negative Supply Voltages
D Input Clamp Diodes for DC Restoration
D Internal Pull–Down Resistors
