The GX4404 is a wideband video multiplexer implemented in bipolar technology. This device is characterized by excellent differential phase and gain in the enabled state, very high off-isolation in the disabled state. Fully buffered unilateral signal paths ensure negligible output to input feedback, while delivering minimal output switching transients through make-before-break switching.
For use in NxM routing matrices, these devices feature a very high, nearly constant input impedance coupled with high output impedance in the disabled state. This allows multiple devices to be paralleled at the inputs and outputs without additional circuitry.
The chip is disabled when a logic HIGH is applied to the CS control pin. In this case, regardless of the ADDRESS data, the output of the device assumes a high impedance state. Individual PNP to VCC TALLY outputs provide positive indication of crosspoint selection.
All logic inputs are TTL and 5V CMOS compatible. Supply voltages can be between ±4.5 to ±5.5 volts.
