Overview
HD74HCT245 Octal Bus Transceivers (with 3-state outputs) Description This device has an active low enable input G and a direction control input (DIR).
When DIR is high, data flows from the A inputs to the B outputs.
When DIR is low, data flows from the B inputs to the A outputs.
The HD74HCT245 transfers true data from one bus to the other.
This device does not have schmitt trigger inputs.
