HD74HCT241

HD74HCT241 Octal Buffers/Line Drivers/Line Receivers (with noninverted 3-state outputs) Description The HD74HCT241 is a noninverting buffer and has one active low enable and one active high enable. Each enable independently controls 4 buffers. This device does not have schmitt trigger inputs.
