description
These octal buffers and line drivers are designed
to have the performance of the popular ’HC240
series and to offer a pinout with inputs and outputs
on opposite sides of the package. This
arrangement greatly facilitates printed circuit
board layout.
The 3-state control gate is a 2-input NOR. If either
output-enable (OE1 or OE2) input is high, all eight
outputs are in the high-impedance state. The
’HCT541 provide true data at the outputs.
The SN54HCT541 is characterized for operation
over the full military temperature range of –55°C
to 125°C. The SN74HCT541 is characterized for
operation from –40°C to 85°C.
