SGS Thomson Microelectronics BC177 Datasheet
BC177
LOW NOISE GENERAL PURPOSE AUDIOAMPLIFIERS
DESCRIPTION
The BC177 is a silicon planar epitaxial PNP
transistors in TO-18 metal case. It is suitable for
use in driver stages, low noise input stages and
signal processing circuits of television reveivers.
The NPN complementisBC107.
