Two inputs are provided with sink chip clamp function which adjust the DC level of video signal. The other input of transistor open base can make control of luminance signal. This video switch can be connected to TV monitor directly, as it has 6dB amplifier circuit internally. NJM2265 is a high performance video switch which is operated with 5V supply voltage. ■ FEATURES ● Wide Operating Voltage (4.75V to 13V) ● 3 Input, 1 – Output ● Internal 6 dB Amplifier Circuit ● Internal Sink Chip Clamp Function (VIN1, VIN2) ● Internal Luminance Signal Control Function (VIN3) ● Crosstalk 65dB (at 4.43MHz) ● Package Outline DIP8, DMP8, SIP8 ● Bipolar Technology ■ PACKAGE OUTLINE NJM2265D NJM2265M NJM2265L ■ APPLICATIONS ●VCR, Video Camera, AV-TV, Video Disc Player. ■ BLOCK DIAGRAM Ver.2004-02-17 -1- NJM2265 ■ ABSOLUTE MAXIMUM RATINGS PARAMETER (Ta=25°C) SYMBOL + RATINGS UNIT V mW mW mW Supply Voltage Power Dissipation V PD Operating Temperature Range Topr 15 (DIP8) 500 (DMP8) 300 (SIP8) 800 -40 to +85 Storage Temperature Range Tstg -40 to +125 °C °C (V+=5V, Ta=25±2°C) ■ ELECTRICAL CHARACTERISTICS PARAMETERS SYMBOLS TEST CONDITIONS + MIN.

This IC requires 0.1uF capacitor between INPUT and GND, 1MΩ resistance between INPUT and GND for clamp type input at mute mode.
