具有三态输出的 18 位通用总线收发器 56-TSSOP -40 to 85
These 18-bit universal bus transceivers consist of storage elements that can operate either as D-type latches or D-type flip-flops to allow data flow in transparent or clocked modes.
Data flow in each direction is controlled by output-enable OEAB and , 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 low-to-high transition of CLKAB. When OEAB is high, the outputs are active. When OEAB is low, the outputs are in the high-impedance state.
Data flow for B to A is similar to that of A to B but uses, LEBA, and CLKBA. The output enables are complementary OEAB is active high and is active low.
To ensure the high-impedance state during power up or power down, OE should be tied to GND through a pulldown resistor and should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sourcing/current-sinking capability of the driver.
