description

These octal buffers and line 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 ’ACT241 are organized as two 4-bit

buffers/drivers with separate complementary

output-enable (1OE and 2OE) inputs. When 1OE

is low or 2OE is high, the device passes

noninverted data from the A inputs to the

Y outputs. When 1OE is high or 2OE is low, the

outputs are in the high-impedance state.

The SN54ACT241 is characterized for operation

over the full military temperature range of –55

°C

to 125

°C. The SN74ACT241 is characterized for

operation from –40

°C to 85°C.
