VL82C104 PC/AT-Compatible Data Buffer

The VL82C104 PC/AT-Compatible Data Buffer provides a 16-bit CPU data bus I/O as well as 40 buffered drivers. The buffered drivers consist of 16 bi- directional system data bus drivers, each capable of sinking 20 mA (50 'LS loads) of current; eight bidirectional peripheral bus drivers, each capable of sinking 8 mA (20 'LS loads) of current; and 16 memory data bus drivers, each capable of sinking 8 mA (20 'LS loads) of current. The VL82C104 also generates the parity error signal for the system.

The device is manufactured with VLSI's advanced high-performance CMOS process and is available in JEDEC-standard 84-pin plastic leaded chip carrier (PLCC) package. The VL82C104 is part of the PC/AT-compatible chips sets available from VLSI.
