GENERAL DESCRIPTION

The AD9300 is a monolithic high speed video signal multiplexer

usable in a wide variety of applications.

Its four channels of video input signals can be randomly

switched at megahertz rates to the single output. In addition,

multiple devices can be configured in either parallel or cascade

arrangements to form switch matrices. This flexibility in using

the AD9300 is possible because the output of the device is in a

high-impedance state when the chip is not enabled; when the

chip is enabled, the unit acts as a buffer with a high input im-

pedance and low output impedance.

An advanced bipolar process provides fast, wideband switching

capabilities while maintaining crosstalk rejection of 72 dB at

10 MHz. Full power bandwidth is a minimum 27 MHz. The

device can be operated from

±10 V to ±15 V power supplies.

PIN DESIGNATIONS

DIP

LCC and PLCC

The AD9300K is available in a 16-pin ceramic DIP and a

20-pin PLCC and is designed to operate over the commercial

temperature range of 0

°C to +70°C. The AD9300TQ is a

hermetic 16-pin ceramic DIP for military temperature range

(–55

°C to +125°C) applications. This part is also available pro-

cessed to MIL-STD-883. The AD9300 is available in a 20-pin

LCC as the model AD9300TE, which operates over a tempera-

ture range of –55

°C to +125°C.

The AD9300 Video Multiplexer is available in versions compli-

ant with MIL-STD-883. Refer to the Analog Devices Military

Products Databook or current AD9300/883B data sheet for de-

tailed specifications.
