Introduction

The HA4404B is a very wideband 4 x 1 crosspoint switch designed for professional video switching, HDTV, computer monitor routing, and other high-performance applications. The circuit features very low power consumption (105mW when enabled, 4mW when disabled), excellent differential gain and phase, and very high off-isolation. When disabled, the output switches to a high-impedance state, making the HA4404B ideal for routing matrix applications.

The HA4404B requires no external current sources and features fast switching with symmetrical slew rates. The count output is an open-collector PNP transistor, providing an indication of crosspoint selection.
