description

These

octal

buffers/drivers

are

designed

specifically to improve 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. These devices feature high

fan-out and improved fan-in.

The -1 version of SN74ALS241C is identical to the

standard version, except that the recommended

no -1 version of the SN54ALS241C.

The

SN54ALS241C

and

SN54AS241A

are

characterized for operation over the full military

temperature range of – 55

°C to 125°C. The

SN74ALS241C

and

SN74AS241A

are

characterized for operation from 0

°C to 70°C.
