General Description
This Schottky memory is organized in the popular 512
words by 8 bits configuration. A memory enable input is pro-
vided to control the output states. When the device is en-
abled, the outputs represent the contents of the selected
word. When disabled, the 8 outputs go to the "OFF" or high
impedance state.
PROMs are shipped from the factory with lows in all loca-
tions. A high may be programmed into any selected location
by following the programming instructions.
Features
I: Advanced titanium-tungsten (T i-W) fuses
II Schottky-clamped for high speed
Address access down to-35 ns max
Enable aattyss-25 ns max
Enable rotrovery--25 ns max
I: PNP inputs for reduced input loading
I: All DC and AC parameters guaranteed over
temperature
" Low voltage TRl-SAFETM programming
I: TRI-STATE© outputs
