5C180

The intel 5C180 PLD(programmable logic device) is a CMOS, 48-macrocell, general-purpose PLD.This user-cistomizable logic device is available in a 68-pin PLCC package and has the benefits of low power and increased flexibility.

Features of the 5C180 are:(1)high-performance LSI semicustom logic alternative for TTL and 74HC SSI and MSI logic; (2)48 macrocells with programmable I/O architecture; up to 64 inputs(16 dedicated , 48 I/O) or 48 outputs; (3)high speed tPD(max) 70 ns, 20.8 MHz plpelined , 16.1 MHz w/feedback; (4)dual feedback signals allowing I/O pins to be used for buried logic and dedicated input.

Well, this is a simple introduction to this kind of 5C180, if you are interested in it and want to know more about it, please pay attention to our web!
