简述:
Octal buffer/line driver; 3-state
-
描述:
The 74AHCT541A is an 8-bit buffer/line driver with 3-state outputs and TTL inputs. The device features two output enables (OE1 and OE2). A HIGH on OEn causes the associated outputs to assume a high-impedance OFF-state.
Designed to operate over a VCC range from 4.5 V to 5.5 V, the inputs are TTL compatible, which allows the device to be used to translate from 3.3 V to 5 V.
Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times.
This device is fully specified for partial Power-down applications using IOFF. The IOFF circuitry disables the output, preventing the damaging backflow current through the device when it is powered down.
