DESCRIPTIO

The LT

bandwidth and excellent video characteristics. The low

differential gain and phase, wide bandwidth, and 30mA

output drive current make the LT1227 well suited to drive

cables in video systems.

A shutdown feature switches the device into a high imped-

ance, low current mode, allowing multiple devices to be

connected in parallel and selected. Input to output isola-

tion in shutdown is 70dB at 10MHz for input amplitudes up

to 10V

or open drain logic and takes only 4 s to enable or disable.

The LT1227 comes in the industry standard pinout and

can upgrade the performance of many older products. For

a dual or quad version, see the LT1229/1230 data sheet.

The LT1227 is manufactured on Linear Technology’s

proprietary complementary bipolar process.
