SN74ALVCH16863数据手册集成电路（IC）的缓冲器驱动器接收器收发器规格书PDF

描述 Description

This 18-bit bus transceiver is designed for 1.65-V to 3.6-V VCC operation. The SN74ALVCH16863 is an 18-bit noninverting transceiver designed for synchronous communication between data buses. The control-function implementation minimizes external timing requirements. The SN74ALVCH16863 can be used as two 9-bit transceivers or one 18-bit transceiver. They allow 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 output-enable (OEAB\\ or OEBA\\) inputs. 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 SN74ALVCH16863 is characterized for operation from -40°C to 85°C.
