ELECTRICAL SPECIFICATIONS

The DS5002FP adheres to all AC and DC electrical specifications published for the DS5001FP.

ABSOLUTE MAXIMUM RATINGS

Voltage Range on Any Pin Relative to Ground……………………………………………………….-0.3V to (VCC + 0.5V)

Voltage Range on VCC Relative to Ground……………………………………………………………………-0.3V to +6.0V

Operating Temperature Range………………………………………………………………………………..-40°C to +85°C

Storage Temperature* ...……………………………………………………………………………………..-55

°C to +125°C

Soldering Temperature……………………………………………………….....See IPC/JEDEC J-STD-020 Specification

This is a stress rating only and functional operation of the device at these or any other conditions beyond those indicated in the operation

sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods of time can affect reliability.

*Storage temperature is defined as the temperature of the device when VCC = 0V and VLI = 0V. In this state the contents of SRAM are not

battery-backed and are undefined.
