description  
The TMS45160 series are high-speed, 4194304-bit dynamic random-access memories organized as 262144  
words of 16 bits each. The TMS45160P series are high-speed, low-power, self-refresh 4194304-bit dynamic  
random-access memories organized as 262144 words of 16 bits each. They employ state-of-the-art EPIC  
(Enhanced Performance Implanted CMOS) technology for high performance, reliability, and low power at low  
cost.  
These devices feature maximum RAS access times of 60 ns, 70 ns, and 80 ns. Maximum power dissipation  
is as low as 770 mW operating and 11 mW standby on 80-ns devices. All inputs and outputs, including clocks,  
are compatible with Series 74 TTL. All addresses and data-in lines are latched on chip to simplify system design.  
Data out is unlatched to allow greater system flexibility.  
The TMS45160 and TMS45160P are each offered in a 40-lead plastic surface-mount SOJ package (DZ suffix)  
and a 40/44-lead plastic surface-mount small-outline (TSOP) package (DGE suffix). These packages are  
characterized for operation from 0°C to 70°C.

Products conform to specifications per the terms of Texas Instruments  
standard warranty. Production processing does not necessarily include  
testing of all parameters.
