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.

The SN74ALVCH16500 is characterized for operation from –40°C to 85°C.
