<2708 (looks like 12 volts according to a spec sheet in one of my
<books.)
2708 is three voltage for operation (+5, +12, -5) programming is
for programming CS/ must be 12.0v and program pulse is 26v
<2716 25 volts
27c16 12.5
TI2532 25v differing pinout and programming spec.
<2732 25 volts
<2732A 21 volts
<2732B 12.5 volts
<2764 21 volts
<27C64 21 volts
<2764A 12.5 volts
Later ones are generally 12.5v. Some require different Vcc when
programming as well. Also the part numbers given do not always match
given vendors for a stated programming voltage
