The HA4344B is a very wide bandwidth 4 x 1 crosspoint
switch ideal for professional video switching, HDTV, com-
puter display routing, and other high performance applica-
tions. This circuit features very low power dissipation,
excellent differential gain and phase, high off isolation, sym-
metric slew rates, fast switching, and latched control signals.
When disabled, the output is switched to a high impedance
state, making the HA4344B ideal for matrix routers.
The latched control signals allow for synchronized channel
switching. When CK1 is low the master control latch loads the
next switching address (A0, A1, CS), while the closed (assum-
ing CK2 is the inverse of CK1) slave control latch maintains the
crosspoint in its current state. CK2 switching low closes the
master latch (with previous assumption), loads the now open
slave latch, and switches the crosspoint to the newly selected
channel. Channel selection is asynchronous (changes with any
control signal change) if both CK1 and CK2 are low.
