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

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
