DESCRIPTION
The LVT2245 is a high-performance BiCMOS product designed for
V
This device is an octal transceiver featuring non-inverting 3-State
bus compatible outputs in both send and receive directions. The
control function implementation minimizes external timing
requirements. The device features an Output Enable (OE) input for
easy cascading and a Direction (DIR) input for direction control.
The 74LVT2245 is designed with 30 series resistance in both the
High and Low states of the output. This design reduces line noise in
applications such as memory address drivers, clock drivers, and bus
transceivers/transmitters.
