description
This octal buffer and line driver is designed
specifically to improve both the performance and
density of 3-state memory address drivers, clock
drivers,
and
bus-oriented
receivers
and
transmitters. The 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 SN74ALS1240 is characterized for operation from 0
°C to 70°C.
