Description:
The NTE1507 is an integrated circuit in a 16–Lead 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 is switched to a low logic level. All outputs are at low logic levels at a typical input voltage of 2000mV. The threshold–adjust pin 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 is directly cascadable requiring only two external resistors to establish a zero–reference level voltage for the cascade input. The maximum number of devices 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 low–precision meters, warning–signal indicators, A/D converters, feedback regulators, pulse shapers, delay elements, and for automatic range switching. The open–emitter outputs are capable of sourcing currents up to 25mA and may be operated at voltages up to 35V. The power outputs are suitable for driving a variety of display elements such as vacuum flourescent displays, LED’s, or filament lamps. The outputs may also drive digital integrated logic such as CMOS or other high–level logic.

Features:
• 10 Comparators to Digitize Analog Input Signals
• Cascade Feature Allows Stacking Output Display Strings
• Threshold Intervals Adjustable from 200mV to 100mV
• Open–Emitter Outputs Capable of Sourcing up to 25mA and Withstanding up to 35V
• Supply Voltage Range of 10V to 35V (VCC2)
