UPD22100 Datasheet, PDF (1/16 Pages) NEC – CROSSPOINT SWITCH WITH CONTROL MEMORY CMOS IC

DATA SHEET
MOS INTEGRATED CIRCUIT
µPD22100, 22148
CROSSPOINT SWITCH WITH CONTROL MEMORY
CMOS IC
The µPD22100 consists of 16 crosspoint switches organized in 4 rows and 4 columns, and the µPD22148 consists
of 32 crosspoint switches organized in 4 row and 8 columns. Any of the 16 or 32 switches can be selected by applying
appropriate address. The selected crosspoint turns on if during strobe and data In are high and turns off if during
strobe and data In are low.
