DS1678 Real-Time Event Recorder

ABSOLUTE MAXIMUM RATINGS

Voltage Range on Any Pin Relative to Ground……………………………………………..-0.3V to +6.0V

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

Storage Temperature Range…………………………………………………………….…-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 above those indicated in the operation

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

reliability.

RECOMMENDED DC OPERATING CONDITIONS

(VCC = VCC(MIN) to VCC(MAX), TA = -40°C to +85°C, unless otherwise noted. Typical values are at nominal

supply voltage and TA = +25°C, unless otherwise noted.) (Note 1)
