BCD–to–Seven–Segment Decoder Driver
Description:
The NTE2032 is a monolithic integrated circuit in a 16–Lead DIP type package that performs the
BCD–to–seven–segment decoding function and features constant–current segment drivers. When
used with the NTE2054 A/D converter, the NTE2032 provides a complete digital readout system with
a minimum number of external parts.
Features:
D TTL Compatible Input Logic Levels
D 25mA (Typ) Constant Current Segment Outputs
D Eliminates Need for Output Current Limiting Resistors
D Pin Compatible with Other Industry Standard Decoders
