Description
The 74LX1G07 is a low voltage CMOS single buffer/driver (open drain) fabricated with submicron silicon gate and double-layer metal wiring C2MOS technology.
The internal circuit composed of 2 stages including buffer output, provides high noise immunity and stable output.
Power down protection is provided on input and 0 to 7 V can be accepted on input with no regards to the supply voltage. This device can be used to interface 5 to 3 V.

Maximum rating |
|
|
Stressing the device above the rating listed in the “Absolute maximum ratings” table may cause permanent damage to the device. These are stress ratings only and operation of the device at these or any other conditions above those indicated in the operating sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Refer also to the STMicroelectronics SURE Program and other relevant quality documents.
