over operating free-air temperature range (unless otherwise noted)(1)
MIN MAX UNIT
VS = (VS+) – (VS–) Supply voltage(2) 14 V VSO = (VSO+) – (VSO–) Maximum dVS/dT for supply turn-on and turn-off 0.1 V/µs IN Input (VS+) to (VS–) – 0.5 V CLH Positive Clamp Mid-supply VS+ CLL Negative Clamp VS– Mid-supply V Input Clamp Diode 100 mA TJ Junction temperature 150 °C Tstg Storage temperature –65 150 °C (1) Operation outside the Absolute Maximum Ratings may cause permanent device damage. Absolute maximum ratings do not imply functional operation of the device at these or any other conditions beyond those listed under Recommended Operating Conditions. If briefly operating outside the Recommended Operating Conditions but within the Absolute Maximum Ratings, the device may not sustain damage, but it may not be fully functional. Operating the device in this manner may affect device reliability, functionality, performance, and shorten the device lifetime. (2) VSO and VS should be tied to the same potential. VSO and VS are internally connected to each other through back to back diodes.
6.2 ESD Ratings VALUE UNIT
Human body model (HBM), per ANSI/ESDA/JEDEC JS-001(1) ±1000 V(ESD) Electrostatic discharge V Charged device model (CDM), per ANSI/ESDA/JEDEC JS-002(2) ±500 (1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. (2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.
6.3 Recommended Operating Conditions
over operating free-air temperature range (unless otherwise noted)
MIN NOM MAX UNIT
Dual Supply voltage ±4.5 ±5 ±6.5 V VS = (VS+) – (VS–)(1) Single Supply voltage 9 10 13 V TA Ambient temperature –40 25 85 °C (1) BUF802 can be used with any possible combination of VS+ and VS– , provided the recommended operating condition is not exceeded
