LM1044 Analog Video Switch
General Description
Primarily intended for but not restricted to the switching of
video signals the LM1044 is a monolithic DC controlled an-
alog switch with buffered outputs allowing the selection of
three 5 MHz bandwidth 6 dB gain channels or two
RGBaSync 30 MHz bandwidth 0 dB gain channels Chan-
nel selection is achieved via latched TTL compatible logic
inputs which may be controlled by microprocessor derived
signals The device is supplied in a 24 pin dual in line plastic
package
Features
