Intel 8282

The Intel 8282 is an 8-bit latch, which was developed primarily for the Intel-8086/8087/8088/8089-processors. The component comes in 20-pin DIL package. It was licensed to companies such as NEC and Siemens. With the ROM-less versions of the MCS-48 and MCS-51 microcontroller compact systems with external ROM / EPROM can be realized. The 8282 can also be used in 8080/8085-systems replacing the 8212. If OE is connected to GND, the chip is selected. STB (Strobe) is connected to the pin ALE of the processor and takes over the address data from the multiplexed address-/databus. The 8283 has the same functionality, but the data is inverted. In 1980 the Intel 8282 and I8282 version was available for 5.55 USD and 16.25 USD in quantities of 100 respectively.
