NTE731
Integrated Circuit
TV Video Signal Processor
Description:
The NTE731 is an integrated circuit in a 16Lead DIP type package and performs many of the func-
tions which are often collectively referred to as the video “jungle”. This device provides keyed AGC
for the tuner (forward and/or reverse) and the video IF (reverse), furnishes stripped synchronization
signals in both polarities, and provides lowimpedance video and noisecancelled video output
signals. The NTE731 is used as a lowcost, highquality circuit in monochrome as well as color
TV receivers.
The circuit combines high performance with economy by eliminating the need for either AGC or
noise threshold adjustments. Positive noise gating and high sync. separator gain assure excellent
performance over a wide range of signal conditions.
Features:
D HighImpedance Video Input
D LowImpedance EmitterFollower Video Output

D Delayed Forward AGC for NPN Bipolar Tuner
D Delayed Reverse AGC for PNP, MOSFET, or Tube Tuner
D Positive and Negative Sync Outputs
D Preset Noise Detector
D SingleSupply Operation
