Product Details

The LT1204 is a 4-input video multiplexer designed to drive 75Ω cables and easily expand into larger routing systems. Wide bandwidth, high slew rate, and low differential gain and phase make the LT1204 ideal for broadcast quality signal routing. Channel separation and disable isolation are greater than 90dB up to 10MHz. The channel-to-channel output switching transient is only 40mVP-P, with a 50ns duration, making the transition imperceptible on high quality monitors.

A unique feature of the LT1204 is its ability to expand into larger routing matrices. This is accomplished by a patent pending circuit that bootstraps the feedback resistors in the disable condition, raising the true output impedance of the circuit. The effect of this feature is to eliminate cable misterminations in large systems.

The large input and output signal levels supported by the LT1204 when operated on ±15V supplies make it ideal for general purpose analog signal selection and multiplexing. A shutdown feature reduces the supply current to 1.5mA.
