4 / 14 page ![]() ©1994 Fairchild Semiconductor Corporation www.fairchildsemi.com 74LCX240 Rev. 1.6.0 3 Absolute Maximum Ratings Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only. Note: 2. IO Absolute Maximum Rating must be observed. Recommended Operating Conditions(3) The Recommended Operating Conditions table defines the conditions for actual device operation. Recommended operating conditions are specified to ensure optimal performance to the datasheet specifications. Fairchild does not recommend exceeding them or designing to absolute maximum ratings. Note: 3. Unused inputs must be held HIGH or LOW. They may not float. Symbol Parameter Rating VCC Supply Voltage –0.5V to +7.0V VI DC Input Voltage –0.5V to +7.0V VO DC Output Voltage Output in 3-STATE –0.5V to +7.0V Output in HIGH or LOW State(2) –0.5V to VCC + 0.5V IIK DC Input Diode Current, VI < GND –50mA IOK DC Output Diode Current VO < GND –50mA VO > VCC +50mA IO DC Output Source/Sink Current ±50mA ICC DC Supply Current per Supply Pin ±100mA IGND DC Ground Current per Ground Pin ±100mA TSTG Storage Temperature –65°C to +150°C Symbol Parameter Min.
