Product overview
The UT64BS1X433 Matrix-A is a 64-channel, 1:4 bus switch for processor interfaces to asynchronous SRAM and PROM. It isolates up to four banks of 64 I/O connections to reduce bus loading. The device supports two selection modes: one selects among four banks, while another independently controls two pairs of banks for different memory configurations. Transmission-gate channels provide bidirectional operation, and bus holders maintain output states when channels are deselected. The switch operates from a single 3.3 V supply and passes signals between ground and the supply voltage.
