description
These octal buffers and line drivers are designed
specifically to improve both the performance and
density of 3-state memory address drivers, clock
drivers,
and
bus-oriented
receivers
and
transmitters. The ’HCT244 are organized as two
4-bit buffers/drivers with separate output-enable
(OE) inputs. When OE is low, the device passes
noninverted data from the A inputs to the
Y outputs. When OE is high, the outputs are in the
high-impedance state.
The SN54HCT244 is characterized for operation
over the full military temperature range of –55
°C
to 125
°C. The SN74HCT244 is characterized for
operation from –40
°C to 85°C.
