NTE1177
Integrated Circuit
TV Luminance Processor
Description:
The NTE1177 is a monolithic silicon integrated circuit in a 14–Lead DIP type package that performs
the luminance processing functions of amplification; contrast, brightness and peaking control; blank-
ing; and black–level clamping.

Note 1. Although the NTE1177 is rated for maximum dissipation of 750mW, it is recommended that
the current into Pin13 be limited by external circuit resistance to 39mA for a typical voltage
at Pin13 of 11.8V.
