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 (8035/8039 and 8031/8032) compact systems with external ROM / EPROM can be realized. The 8282 can also be used in
8080/
8085-systems replacing the
8212. If (''Output Enable'') is connected to GND, the chip is selected. STB (''Strobe'') is connected to the pin ALE (''Address Latch Enable'') 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 (industrial grade) version was available for 5.55 USD and 16.25 USD in quantities of 100 respectively.

Intel 8282 is functionally identical to
74573 or 74373 octal latch, although the pinout differ slightly.
