具有三态输出的 18 位通用总线收发器 56-SSOP -40 to 85
This 18-bit universal bus transceiver is designed for 1.65-V to 3.6-V VCC operation.
Data flow in each direction is controlled by output-enable OEAB and OEBA\\\\, latch-enable LEAB and LEBA, and clock CLKAB\ and CLKBA\\\\ inputs. For A-to-B data flow, the device operates in the transparent mode when LEAB is high. When LEAB is low, the A data is latched if CLKAB\ is held at a high or low logic level. If LEAB is low, the A data is stored in the latch/flip-flop on the high-to-low transition of CLKAB\\\\. Output-enable OEAB is active high. When OEAB is high, the B-port outputs are active. When OEAB is low, the B-port outputs are in the high-impedance state.
Data flow for B to A is similar to that of A to B, but uses OEBA\, LEBA, and CLKBA\\\\. The output enables are complementary OEAB is active high, and OEBA\ is active low.
To ensure the high-impedance state during power up or power down, OEBA\ should be tied to VCC through a pullup resistor, and OEAB should be tied to GND through a pulldown resistor; the minimum value of the resistor is determined by the current-sinking/current-sourcing capability of the driver.
Active bus-hold circuitry holds unused or floating data inputs at a valid logic state.
