Programmable Array Logic (PAL) is a family of programmable logic device semiconductors used to implement logic functions in digital circuits introduced by Monolithic Memories, Inc. (MMI) in March 1978
Early PALs were 20-pin DIP components fabricated in silicon using bipolar transistor technology with one-time programmable (OTP) titanium-tungsten programming fuses. Later devices were manufactured by Cypress, Lattice Semiconductor and Advanced Micro Devices using CMOS technology.
The original 20 and 24-pin PALs were denoted by MMI as medium-scale integration (MSI) devices.
PAL devices consisted of a small PROM (programmable read-only memory) core and additional output logic used to implement particular desired logic functions with few components.
Using specialized machines, PAL devices were “field-programmable”.
These parts came to us as part of a lot of surplus stock from a large Milspec type OEM and have been kept in storage for some time (date coded 8944), we have therefore classified them as ‘new other’. They are however unused and in pristine condition, stored with us still tubed and in original packaging, and, as with all our products they come with a full guarantee. The photograph’s are of the actual chips we hold in stock.
If you have similar items to this, or indeed any electronic components that are surplus to requirements please contact us with details.
