MBM2764 & 27C64 eproms - Same?

[Paul Berger (Canada)]

Logically they are the same, have the same pinout, but they are from different logic families. The MBM2764 is a NMOS part while a 27C64 is a CMOS part. The big difference it the NMOS part will draw several times the current the CMOS part, but we are not talking about big load the CMOS part is in the range of 20 to 25mA when operating where as the NMOS part is abut 150mA.
