74VHC245; 74VHCT245
Octal bus transceiver; 3-state
The 74VHC245; 74VHCT245 are high-speed Si-gate CMOS devices.
The 74VHC245; 74VHCT245 are octal transceivers featuring non-inverting 3-state bus compatible outputs in both send and receive directions.
The 74VHC245; 74VHCT245 feature an output enable input (OE), for easy cascading, and a send and receive direction control input (DIR).
OE controls the outputs so that the buses are effectively isolated.
Features and benefits
Balanced propagation delays
All inputs have Schmitt-trigger action
Inputs accept voltages higher than VCC
- Input levels:
The 74VHC245 operates with CMOS input level
