XBLW SN74HC/HCT366
Hex Buffer/Line Driver; 3-state; Lnverting
General Description
The SN74HC/HCT366 is a hex inverting buffer/line driver with 3-state outputs controlled by the output
—
—
enable inputs (OEn). A HIGH on OEn causes the outputs to assume a high impedance OFF-state. Inputs
include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess
of VCC.
Features
Input levels:
For SN74HC366: CMOS level
For SN74HCT366: TTL level
Inverting outputs
Specified from -40℃ to +125℃
