TECHNICAL DATA
IN74ALS240A
OCTAL BUFFER / DRIVER
WITH 3-STATE OUTPUTS
This octal buffer/driver is designed specially to
improve both the performance and density of 3-state
memory address drivers, clock drivers and bus-
oriented receivers and transmitters. When this device is
used with the 鈥楢LS241, 鈥楢S241A, 鈥楢LS244 and
AS244A, the circuit designer has a choice of selected
combinations of inverting and noninverting outputs,
symmetrical active-low output-enable (OE) inputs and
complementary OE and OE inputs. This device features
high fan-out and improved fan-in.
The IN74ALS240A is characterized for operation from
