The Intel 8283 is an 8- bit latch, which was primarily developed for the Intel-8086/8087/8088/8089-Prozessoren. The block is supplied in 20-pin DIP. He was licensed to NEC and Siemens among others. Is OE ( Output Enable ) is connected to GND, the block is selected. STB (Strobe ) is connected to the terminal ALE ( Address Latch Enable ) of the processor and takes over the address data from the multiplexed Adress-/Datenbus. The incoming data is - in contrast to 8282 - inverted.
