DS1323
ABSOLUTE MAXIMUM RATINGS
Voltage Range on Any Pin Relative to Ground.......................................................................... -0.3V to +6.0V
Operating Temperature Range................................................................................................... -40°C to +85°C
Storage Temperature Range .................................................................................................... -55°C to +125°C
Lead Temperature (soldering, 10s)......................................................................................................... +300°C
Soldering Temperature (reflow) ............................................................................................................. +260°C
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 reliability.
PACKAGE THERMAL CHARACTERISTICS (Note 1)
TSSOP
Junction-to-Ambient Thermal Resistance (θ_JA).................................................................................73.8°C/W
Junction-to-Case Thermal Resistance (θ_JC) ..........................................................................................20°C/W
Note 1: Package thermal resistances were obtained using the method described in JEDEC specification
JESD51-7, using a four-layer board. For detailed information on package thermal considerations,
