82C88 is a CMOS bus controller produced by Intersil. It is compatible with Bipolar 8288 and is compatible with 80C86/80C88, 80186/80188, 8086/8088, 8089. 82C88 provides three-state command outputs, has bipolar drive capability, uses scaled SAJI IV CMOS process, single 5V power supply, and low power operation.
The Intersil 82C88 is a high performance CMOS Bus Controller manufactured using a self-aligned silicon gate CMOS process. It provides the control and command timing signals for various processors such as 80C86, 80C88, 8086, 8088, 8089, 80186, and 80188 based systems. The high output drive capability of the 82C88 eliminates the need for additional bus drivers.
