DESCRIPTION
The LVT2244 is a high-performance BiCMOS product designed for
V
This device is an octal buffer that is ideal for driving bus lines. The
device features two Output Enables (OE1, OE2), each controlling
four of the 3-State outputs.
The 74LVT2244 is designed with 30 series resistance in both the
High and Low states of the output. This design reduces the line
noise in applications such as memory address drivers, clock drivers
and bus receivers/transmitters.
