OCTAL BUS TRANSCEIVERS
WITH 3-STATE OUTPUTS
„ DESCRIPTION
The U74AHC640 is a octal bus transceivers with 3-state
outputs. It is designed for asynchronous two-way communication
between data buses. Depending on the direction-control (DIR) input,
data are transmitted from the A bus to the B bus or from the B bus to
the A bus.
When OE is high, the buses are effectively isolated. When
OE is low, the buses are enable.
„ FEATURES
* Wide Supply Voltage Range from 2V to 6V
* Typical tPD of 8ns at 6V, CL=50pF
* Low Power Consumption, ICC = 8μA (Max) at 5.5V
* ±7.8mA Output Driver at 6V

Note: 1. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
2. Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
