HD74HCT640/HD74HCT643
Octal Bus Transceivers (with 3-state outputs)
ADE-205-562 (Z)
1st. Edition
Sep. 2000
Description
Both the HD74HCT640 and the HD74HCT643 have one active low enable input (G), and a direction
control (DIR). When the DIR input is high, data flows from the A inputs to the B outputs. When DIR is
low, data flows from B to A.
The HD74HCT640 transfers inverted data from one bus to the other. The HD74HCT643 transfers inverted
data from the A bus to the B bus and non-inverted data from the B bus to the A bus.
