NTE2032
Integrated Circuit
BCD鈥搕o鈥揝even鈥揝egment Decoder Driver
Description:
The NTE2032 is a monolithic integrated circuit in a 16鈥揕ead DIP type package that performs the
BCD鈥搕o鈥搒even鈥搒egment decoding function and features constant鈥揷urrent 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.
