(512 x 8) 4096-Bit TTL PROM  
General Description  
Features  
Y
Advanced titanium-tungsten (Ti-W) fuses  
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.  
Y
Schottky-clamped for high speed  
Address accessÐ45 ns max  
Enable accessÐ30 ns max  
Enable recoveryÐ30 ns max  
Y
PNP inputs for reduced input loading  
Y
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.  
All DC and AC parameters guaranteed over  
temperature  
Low voltage TRI-SAFETM programming  
Open-collector outputs
