DESCRIPTIOꢀ  
The P4C1256 is a 262,144-bit high-speed CMOS static  
RAM organized as 32K x 8. The CMOS memory requires  
no clocks or refreshing, and has equal access and cycle  
times. InputsarefullyTTL-compatible. TheRAMoperates  
from a single 5V±10% tolerance power supply.  
with matching access and cycle times. Memory locations  
are specified on address pinsA0 toA14. Reading is accom-  
plished by device selection (CE) and output enabling (OE)  
while write enable (WE) remains HIGH. By presenting the  
address under these conditions, the data in the addressed  
memorylocationispresentedonthedatainput/outputpins.  
The input/output pins stay in the HIGH Z state when either  
CE or OE is HIGH or WE is LOW.  
Access times as fast as 12 nanoseconds permit greatly  
enhanced system operating speeds. CMOS is utilized to  
reduce power consumption to a low level. The P4C1256  
is a member of a family of PACE RAM™ products offering  
fast access times.  
PackageoptionsfortheP4C1256include28-pinDIP,SOJ,  
and TSOP packages. For military temperature range,  
Ceramic DIP and LCC packages are available.
