The MT88V32 is a digitally programmable (TTL levels) 8x4 crosspoint switch that is designed to control wide-band analog (video) signal. Each of the 32 nodes of the switching matrix has a T-switch, this grounds the nodes of all open connections, which greatly reduces feedthrough noise. In order to reduce crosstalk, individual analog signal lines are isolated by interleaving them with ground lines. The two stage programmable latch system allows the state of all switching nodes to be updated simultaneously. The next state of the switch is written into the first stage of the latches through individual write cycles. These changes will not affect the current state of the switch. The STROBE2 control input is used to load the state of all first stage latches to the second stage latches, which updates the complete matrix. Therefore, all 32 switching nodes are updated simultaneously.
