NJM2286M-TE1

NJM2286 2-INPUT 3CHANNEL VIDEO SWITCH ■ GENERAL DESCRIPTION NJM2286 is a switching IC for switching over from one audio or video input signal to another. Internalizing 2 inputs, 1 output, and then each set of 3 can be operated independently. They are a Clamp type", and it can be operated while DC level fixed in position of the video signal. It is a higher efficiency video switch, featuring the operating supply voltage 4.75 to 13.0V, the frequency feature 10MHz, and then the Crosstalk 75dB (at 4.43MHz). ■ FEATURES • 2 Input-1 Output Internalizing 3 Circuits (Clamp type). • Wide Operating Voltage (4.75 to 13.0V) • Crosstalk 75dB (at 4.43MHz) • Wide Bandwidth Frequency Feature 10MHz (2VP-P Input) • Package Outline DIP16, DMP16, SSOP16 • Bipolar Technology ■ PACKAGE OUTLINE NJM2286D NJM2286M NJM2286V ■ APPLICATIONS • VCR, Video Camera, AV-TV, Video Disk Player. ■ BLOCK DIAGRAM NJM2286D NJM2286M Ver.2004-02-17 -1- NJM2286 ■ MAXIMUM RATINGS PARAMETER Supply Voltage (Ta = 25ºC) SYMBOL RATINGS + V 14 (DIP16) (DMP16) UNIT V 700 350 mW mW Power Dissipation PD Operating Temperature Range Topr -40 to +85 ºC Storage Temperature Range Tstg -40 to +125 ºC (V+ = 5V, Ta = 25°C) ■ ELECTRICAL CHARACTERISTICS PARAMETER Operating Current (1) SYMBOL ICC1 MIN.
