DESCRIPTION
The LVT2245 is a high-performance BiCMOS product designed for
VCC operation at 3.3V.
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 30series 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.

NOTES:
1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability.
2. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction
temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150°C.
3. The input and output negative voltage ratings may be exceeded if the input and output clamp current ratings are observed.
