NTE1507

The NTE1507 is an integrated circuit in a 16Lead DIP type package consisting of ten comparators and a reference voltage network to detect the level of a signal at the analog input. Output Q1 is switched to a low logic level at a typical input voltage of 200mV with Threshold Adjust open and the cascade input grounded. After each 200mV increment, the next output of NTE1507  is switched to a low logic level. All outputs are at low logic levels at a typical input voltage of 2000mV.

The thresholdadjust pin of NTE1507 allows the user to decrease the input voltage steps from 200mV to 100mV increments by connecting an external resistor from Threshold Adjust to GND. This level detector of NTE1507 is directly cascadable requiring only two external resistors to establish a zeroreference level voltage for the cascade input. The maximum number of NTE1507 that can be cascaded is determined by the threshold level and the maximum input voltages. If the cascade feature is not utilized, the cascade input must be grounded for proper operation.

The NTE1507 is especially designed to detect and indicate analog signal levels and may be used in various industrial, consumer, or automotive applications such as lowprecision meters, warningsignal indicators, A/D converters, feedback regulators, pulse shapers, delay elements, and for automatic range switching. The openemitter outputs are capable of sourcing currents up to 25mA and may be operated at voltages up to 35V. The power outputs of NTE1507  are suitable for driving a variety of display elements such as vacuum flourescent displays, LED's, or filament lamps. The outputs of NTE1507 may also drive digital integrated logic such as CMOS or other highlevel logic.
