General Description
DM74S473 General Description
This Schottky memory is organized in the popular 512 words by 8 bits configuration. A memory enable input is provided to control the output states. When the device is enabled, 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 locations. A high may be programmed into any selected location by following the programming instructions.
DM74S473 Maximum Ratings
If Military/Aerospace specified devices are required, please contact the National Semiconductor Sales Office/Distributors for availability and specifications.
Supply Voltage (Note 2) ......................................0.5V to a7.0V
Input Voltage (Note 2)........................................-1.2V to a5.5V
Output Voltage (Note 2) .....................................-0.5V to a5.5V
Storage Temperature........................................ -65 to a150
Lead Temp. (Soldering, 10 seconds)................................. 300
ESD to be determined
Note 1: Absolute maximum ratings are those values beyond which the device may be permanently damaged. They do not mean that the device may be operated at these values.
Note 2: These limits do not apply during programming. For the programming ratings, refer to the programming instructions.
