Description  
Features  
The PDM41257 is a high-performance CMOS static  
RAM organized as 262,144 x 1 bit. Writing to this  
device is accomplished when the write enable (WE)  
and the chip enable (CE) inputs are both LOW.  
Reading is accomplished when WE remains HIGH  
and CE goes LOW.  
High-speed access times  
Com’l: 7, 8, 10, 12 and 15 ns  
Industrial: 8, 10, 12 and 15 ns  
Low power operation (typical)  
- PDM41257SA  
Active: 400 mW  
Standby: 150 mW  
- PDM41257LA  
Active: 350 mW  
Standby: 25 mW  
The PDM41257 operates from a single +5V power  
supply and all the inputs and outputs are fully TTL-  
compatible. The PDM41257 comes in two versions,  
the standard power version PDM41257SA and a low  
power version the PDM41257LA. The two versions  
are functionally the same and only differ in their  
power consumption.
