Exposure to absolute maximum rating conditions for extended periods of time may affect reliability. DESCRIPTION The DS9034PCX PowerCap is designed to be a lithium power source for Nonvolatile Time-keeping RAMs in Dallas Semiconductor's directly surface-mountable PowerCap Module (PCM) package. After a PowerCap Module Board has been soldered in place and cleaned, the DS9034PCX PowerCap is placed on top of the PCM Board to form a complete PowerCap Module package. The PowerCap is keyed to prevent incorrect attachment. The DS9034PCX can be easily removed by inserting a regular screwdriver into a detachment feature and prying gently outward and upward to release the PowerCap from the PowerCap Module Board. 1 of 3 110999 DS9034PCX POWERCAP ATTACHMENT AND REMOVAL 3. Pushdown and forward with screwdriver while inserting the PowerCap. This action will "open" the attachment feature.
