Features, Applications

The is a high-performance CMOS static RAM organized 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. The PDM41257 operates from a single +5V power supply and all the inputs and outputs are fully TTLcompatible. 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. The PDM41257 is available 24-pin 300-mil plastic SOJ for surface mount applications.

NOTE: 1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability. 2. Appropriate thermal calculations should be performed in all cases and specifically for those where the chosen package has a large thermal resistance (e.g., TSOP). The calculation should be of the form: P * ja, where Ta is the ambient temperature, P is average operating power and ja the thermal resistance of the package. For this product, use the following ja value: SOJ: 83o C/W
