Overview
High Performance 1024x4PROM Ti-W PROM Family 53/635440 53/635441 53/635441 A Features/Benefits • 24 ns typical access time • Reliable Titanium-Tungsten fuses (Ti-W) guarantees greater than 98% programming yields • Low voltage generic programming • Pin compatible with standard SchoHky PROMs • PNP inputs for low input current • Open collector and three-state outputs Applications • Microprogram control stores • Microprocessor program store • Look-up table • Character generator • Code converter • Programmable logic element (PLETM) 10 inputs, 4 outputs, 1024 product terms Description The 53/63S440 and 53/63S441/A are 1024 x 4 bipolar PROMs featuring low input current PNP inputs, full Schottky clamping with open collector or three-state outputs.
The titanium-tungsten fuses store a logical low and are programmed to the high-state.
Special on-chip circuitry and extra fuses provide preprogramming testing which assures high programming yields and high reliability.
The 63 series is specified for operation over the commercial temperature and voltage range.
The 53 series is specified for the military ranges.
Programming The 53/63S440 and 53/63S441/A PROMs are programmed with the same programming alogrithm as all other Monolithic Memories' generic Ti-W PROMs.
For details refer to Monolithic Memories' LSI Data Book.
