M51326P
Analog switch
REJ03F0079-0100Z
Rev.1.0
Sep.22.2003
Description
The M51326P is a semiconductor integrated circuit for use as an analog switch in image-handling equipment. The IC
incorporates two audio switches, one with two and one with three inputs, and one video switch with two inputs. Each
switch is independently controllable.
Features
• Built-in analog switches for use with video signals and stereo audio signals
• Wide video-switch bandwidth: DC to 10 MHz
• Good crosstalk characteristics (for video): 55 dB (typ.) @5 MHz
Applications
• Video equipment
Recommended operating condition
• Power-supply-voltage range: 5 to 14 V
• Rated power-supply voltage: 9 V, 12 V
