Description/Ordering Information

The 8-bit bus transceiver is noninverted with two independently configurable power rails. The SN74LVC8T245 optimizes operation with V_{CCA and}The V CCB is set at port A from 1.65 V to 5.5 V for tracing V_{Common country assessment}。 V_{Cultural Construction Association}Port B accepts any supply voltage from 1.65 V to 5.5 V for tracking V_{Commercial Crime Bureau}。 V_{China Construction Bank}Accepting any 1.65 V supply voltage from 5.5 V, this node allows bidirectional conversion between general-purpose low voltage voltages of any 1.8 volts, 2.5 volts, 3.3 V, and 5.5 volts.

The SN74LVC8T245 is designed for asynchronous communication between data buses. Direction-controlled logic levels (catalog) input and output enable（OE）In either the input of B or port output or one port output or local impedance mode, both output ports go high. The device transmits data bus from A to B bus when port B output is activated, and bus from B to A bus when port A output is activated. The input circuit's B port is always one and enabled, there must be an extra logic high or low level to prevent my application_CCAnd me_{CC area}。

The SN74LVC8T245 is designed to enable control pins (catalogandOE）_forFive offered by CCA.

This device is fully designated for partial power off application using me_finish。 Down me_ShutdownThe output is disabled when the circuit is installed to prevent damage to the current reflow through.

_atThe Vcc isolation feature ensures that if in it_VCC input ground is that all outputs state at high impedance.

To ensure a high impedance state when powering on or off,Operating environmentShould be connected_arriveVCC is passed by a pull-up resistor, and the lowest value of this resistor is the current that is driven by the driver's sinking capacity.
