† Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTE 1: All voltage values are with respect to VSS.

The TMS416400A is a set of 16 777 216-bit dynamic random-access memory (DRAMs) devices organized as 4194304 words of 4 bits each. The TMS41x400A employs state-of-the-art technology for high performance, reliability, and low power.

These devices feature maximum RAS access times of 50-, 60-, and 70 ns. All address and data-in lines are latched on-chip to simplify system design. Data out is unlatched to allow greater system flexibility.

The TMS416400A and TMS417400A are offered in a 24/26-lead plastic surface-mount SOJ package (DJ suffix). This package is designed for operation from 0°C to 70°C.
