总线收发器 Tri-State 16-Bit Bus
This 16-bit dual-octal noninverting bus transceiver is designed for 1.65-V to 3.6-V VCC operation.
The SN74ALVCHR162245 is designed for asynchronous communication between data buses. The control-function implementation minimizes external timing requirements.
This device can be used as two 8-bit transceivers or one 16-bit transceiver. It allows data transmission 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 DIR input. The output-enable OE input can be used to disable the device so that the buses are effectively isolated.
All outputs, which are designed to sink up to 12 mA, include equivalent 26- series resistors to reduce overshoot and undershoot.
To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
The SN74ALVCHR162245 is characterized for operation from -40°C to 85°C.
