Description
The PI74STX1GT02 is a 2-input NOR gate that operates over the
4.5V to 5.5V V
CC
operating range. The input threshhold levels
are TTL compatible. This device can be used for level shifting
from 3V to 5V system.
Pericom’s PI74STX series of products are produced using the
Company’s advanced submicron technology.

Notes:
Absolute maximum ratings are DC values beyond which the device may be damaged or have its useful life impaired. The datasheet
specifications should be met, without exception, to ensure that the system design is reliable over its power supply, temperature, and
output/input loading variables. Pericom does not recommend operation outside datasheet specifications.
1. The input negative voltage and output voltage ratings may be exceeded if the input and output current ratings are observed.
