Maximum Ratings
(Above which useful life may be impaired. For user guidelines, not tested.)
Supply voltage range, VCC ............................................................ 0.5V to +4.6V
Input voltage range, VI ................................................................... 0.5V to +4.6V
Voltage range applied to any output in the
high-impedance or power-off state, VO(1) .............................. 0.5V to +4.6V
Voltage range applied to any output in the
high or low state, VO(1,2) ........................................................ 0.5V to VCC+0.5V
Input clamp current, IIK (VI <0) ...................................................... 50mA
Output clamp current, IOK (VO <0) ................................................. 50mA
Continuous output current, IO ..................................................................... ±50mA
Continuous current through each VCC or GND ............................ ±100mA
Package thermal impedance, θJA(3): Package A ............................ 64°C/W
Package K ........................... 48°C/W
Storage Temperature range, Tstg ................................................. 65°C to 150°C
Note:
Stresses greater than 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 these or any other conditions above those
indicated in the operational sections of this specification
is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect reliability.
Notes:
1. Input & output negative-voltage ratings may be
exceeded if the input and output curent rating are
observed.
2. Output positive-voltage rating may be exceeded up
to 4.6V maximum if theoutput current rating is ob-
served.
3. The package thermal impedance is calculated in ac-
cordance with JESD 51.
