NOTES:
1. All voltages are measured with respect to Vss.
2. Stresses greater than those listed under ‘Absolute Maximum Ratings’ may cause permanent damage to the device.
This is a stress rating for transient conditions only. Functional operation of the device at these or any other conditions
above those indicated in the ‘Operating Range’ of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.
3. Outputs should not be shorted for more than 30 seconds. No more than one output should be shorted at any time.
4. Sample tested only.

DESCRIPTION
TEST CONDITIONS
ILI
Input Leakage Current
VCC = 5.5 V, VIN = 0 V to VCC
ILO
Output Leakage Current (High-Z) VCC = 5.5 V, VOUT = 0 V to VCC
VOH
Output High Voltage
VCC = 4.5 V, IOH = –4 mA
VOL
Output Low Voltage
VCC = 4.5 V, IOL = 8.0 mA
ICCQ
