74LV245ATBQ: Octal bus transceiver; 3-state
The 74LV245AT is an 8-bit transceiver with 3-state outputs. The device features an output
enable (OE) and send/receive (DIR) for direction control.
A HIGH on (OE) causes the outputs to assume a high-impedance OFF-state.
The 74LV245AT is 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.
