18-bit universal bus transceiver with 30 Ohm termination resistor; 3-state
The 74ALVCH162601 is an 18-bit universal transceiver featuring non-inverting 3-state bus compatible outputs in both send and receive directions. Data flow in each direction is controlled by output enable (OEAB and OEBA), and clock (CPAB and CPBA) 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 CPAB is held at a HIGH or LOW logic level. If LEAB is LOW, the A-bus data is stored in the latch/flip-flop on the LOW-to-HIGH transition of CPAB. When OEAB is LOW, the outputs are active. When OEAB is HIGH, the outputs are in the high-impedance state. The clocks can be controlled with the clock-enable inputs (CEBA/CEAB).
Data flow for B-to-A is similar to that of A-to-B but uses OEBA,LEBA and CPBA.
To ensure the high-impedance state during power-down, OEBA and OEAB should be tied to VCC through a pull-up resistor, the minimum value of the resistor is determined by the current-sinking/current-sourcing capability of the driver.
The 74ALVCH162601 is designed with 30 Ω series resistors in both HIGH or LOW output stage.
Active bus hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
