Description
SN74LVC245APW Transceiver Logic IC Supply Voltage Max.:5.5V; Package/Case:20-TSSOP; Leaded Process Compatible:Yes; Logic Type:Transceiver; Peak Reflow Compatible (260 C):Yes; Number of Circuits:8; Series:74LVC RoHS Compliant: Yes
The SN74LVC245APW is an octal Bus Transceiver with 3-state outputs and designed for 1.65 to 3.6V VCC operation. This device is designed for asynchronous communication between data buses. This device transmits data from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control input. The output-enable input can be used to disable the device so the buses effectively are isolated. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pull-up resistor, the minimum value of the resistor is determined by the current-sinking capability of the driver. Inputs can be driven from either 3.3/5V devices. This feature allows the use of this device as a translator in a mixed 3.3/5V system environment. This device is fully specified for partial-power-down applications using IOFF. The IOFF circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.
These octal bus transceivers are designed for 1.65-V to 3.6-V VCC operation. The ’LVC245A devices are designed for asynchronous communication between data buses.
