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
transmitters.
receivers
and
The ’ACT240 are organized as two 4-bit
buffers/drivers with separate output-enable (OE)
inputs. When OE is low, the device passes
inverted data from the A inputs to the Y outputs.
When OE is high, the outputs are in the
high-impedance state.
The SN54ACT240 is characterized for operation
over the full military temperature range of –55
°
C
to 125
°
C. The SN74ACT240 is characterized for
operation from –40

C to 85
