Description:
The NTE1837 is a tuner controller integrated circuit in a 16–Lead DIP type package containing functions such as band switch, inverter, and low–pass filter. This device can be used as a frequency synthesizer or a voltage synthesizer, depending on the external application circuit.

FEATUREs:
● 2–Input, 5–Output Band Switch
● Band Switch (NTE1658) Available by Changing Over C Pin
● High Maximum Output Current, Low Saturation Voltage
● Meet CATV Tuner Requirements
● Frequency Synthesizer or Voltage Synthesizer Application depending on Inverter and Operational Amplifier Connections

Functions:
● Band Switch (Equivalent to the NTE1658: Refer to the Truth Table)
● Inverter
● Low–Pass Filter (Voltage Follower, Operational Amplifier)
