Description:
The NTE2024 is a monolithic integrated circuit intended for 2–digit display such as “numbers” for tV
and “CB” channel selection, and other 0–99 numerical or counting for consumer or industrial indicator
applications. It consists of two independent BCD–to–7 segment decoder/drivers. Two sets of BCD
inputs are buffered with p–n–p differential amplifier stages internally referenced to 1.7V. Each of the
eight input terminals draws less than 15
μ
A and is provided with an internal protection circuit.
Decoding is accomplished with I
2
L ROM’s. The fourteen output terminals are buffered with Darlington
pairs driving common–emitter output transistors. Each output is capable of sinking 25mA for an LED
common–anode display device. The supply–voltage range (V
CC
) is intended to be 4.5V to 6V. The
output voltage (V
O
) must not exceed 12V, which provides for a wide range of common–anode voltage
sources.
