ABSOLUTE MAXIMUM RATINGS
ELECTRICAL CHARACTERISTICS
(VDD = +5V, VH = VDD, VL = 0, TA = TMIN to TMAX. Typical values are at TA = +25°C, unless otherwise noted. Parameters are mea-
sured at TA = +25°C. Values over full temperature range are guaranteed by design.)
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
VDD to GND ............................................................. -0.3V to +6V
DIN, SCLK, CS to GND ............................................-0.3V to +6V
H, L, W to GND...........................................-0.3V to (VDD + 0.3V)
Maximum Continuous Current into
Pins H, L, and W ...........................................................±1mA
Continuous Power Dissipation (TA = +70°C)
8-Pin SOT23 (derate 8.7mW/°C above +70°C)...........697mW
Operating Temperature Range ...........................-40°C to +85°C
Junction Temperature ..................................................…+150°C
Storage Temperature Range .............................-65°C to +150°C
Lead Temperature (soldering, 10s) .................................+300°C
