Description
Wide band analog switch
Manufacturer
MITSUBISHI
Datasheet
DESCRIPTION
The M52756SP is a semiconductor integrated circuit for the
RGBHV interface. The device features switching signals input
from two types of image sources and outputting the signals to
the CRT display, etc. Synchronous signals, meeting a
frequency band of 10kHz to 200kHz, are output at TTL. The
frequency band of video signals is 250MHz, acquiring high-
resolution images, and are optimum as an interface IC with
high-resolution CRT display and various new media.
