Product data sheet
1 General description
The 74LVT2245; 74LVTH2245 is a high-performance BiCMOS product designed for VCC
operation at 3.3 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 input (OE) for easy
cascading and a direction input (DIR) for direction control.
The 74LVT2245; 74LVTH2245 is designed with 30 Ω series resistance in both the HIGH-
state and LOW-state of the output. This design reduces line noise in applications such as
memory address drivers, clock drivers and bus transceivers and transmitters.
