1. General description
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.
