1.0 ELECTRICAL
CHARACTERISTICS
† Notice: Stresses above those listed under “Maximum
Ratings” may cause permanent damage to the device. This is
a stress rating only and functional operation of the device at
Absolute Maximum Ratings †
Voltage on VDD with respect to VSS ............... -0.6V to +7.0V
Voltage on CS, SCK, SDI, SDI/SDO, and
those or any other conditions above those indicated in the
operational listings of this specification is not implied.
Exposure to maximum rating conditions for extended periods
may affect device reliability.
SHDN with respect to VSS ...................................... -0.6V to 12.5V
Voltage on all other pins (PxA, PxW, PxB, and
SDO) with respect to VSS ............................ -0.3V to VDD + 0.3V
Input clamp current, IIK
(VI < 0, VI > VDD, VI > VPP ON HV pins) ......................±20 mA
Output clamp current, IOK
(VO < 0 or VO > VDD) ..................................................±20 mA
Maximum output current sunk by any Output pin
......................................................................................25 mA
Maximum output current sourced by any Output pin
......................................................................................25 mA
Maximum current out of VSS pin .................................100 mA
Maximum current into VDD pin ....................................100 mA
Maximum current into PXA, PXW & PXB pins ............±2.5 mA
Storage temperature ....................................-65°C to +150°C
Ambient temperature with power applied
-40°C to +125°C
Total power dissipation (Note 1) ................................400 mW
Soldering temperature of leads (10 seconds) ............. +300°C
ESD protection on all pins .................................. ≥ 4 kV (HBM),
.......................................................................... 300V (MM)
Maximum Junction Temperature (TJ) ......................... +150°C
Note 1: Power dissipation is calculated as follows:
Pdis = VDD x {IDD - IOH} + {(VDD-VOH) x IOH} + (VOl x IOL)
