† 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 TMS464409 and TMS465409 series are low-voltage, 67108864-bit dynamic random-access memories (DRAMs), organized as 16777216 words of 4 bits each. The TMS464409P and TMS465409P series are high-speed, low-voltage, low-power, self-refresh, 67108864-bit DRAMs, organized as 16777216 words of 4 bits each. Both TMS46x409 and TMS46x409P  sets of devices employ state-of-the-art technology for high performance, reliability, and low power.

These TMS46x409 and TMS46x409P  devices feature maximum RAS access times of 40, 50, and 60 ns. All inputs and outputs, including clocks, are compatible with LVTTL. All addresses and data-in lines are latched on chip to simplify system design. Data out is unlatched to allow greater system flexibility.

The TMS46x409 and TMS46x409P series are offered in a 400-mil, 32-lead plastic surface mount TSOP package (DGC suffix). This package is designed for operation from 0°C to 70°C.
