74ALVCH16646DGG

16-bit bus transceiver/register; 3-state

The 74ALVCH16646 consists of 16 non-inverting bus transceiver circuits with 3-state outputs, D-type flip-flops and control circuitry arranged for multiplexed transmission of data directly from the internal registers. Data on the ‘A’ or ‘B’ bus will be clocked in the internal registers, as the appropriate clock (nCPAB or nCPBA) goes to a HIGH logic level. Output enable (nOE) and direction (nDIR) inputs are provided to control the transceiver function. In the transceiver mode, data present at the high-impedance port may be stored in either the ‘A’ or ‘B’ register, or in both. The select source inputs (nSAB and nSBA) can multiplex stored and real-time (transparent mode) data. The direction (nDIR) input determines which bus will receive data when nOE is active (LOW). In the isolation mode (nOE = HIGH), ‘A’ data may be stored in the ‘B’ register and/or ‘B’ data may be stored in the ‘A’ register.

When an output function is disabled, the input function is still enabled and may be used to store and transmit data. Only one of the two buses, ‘A’ or ‘B’ may be driven at a time.

To ensure the high impedance state during power up or power down, nOE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking/current-sourcing capability of the driver.

Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.

Sample

As a Nexperia customer you can order samples via our sales organization or directly via our Online Sample Store: https://extranet.nexperia.com.

Sample orders normally take 2-4 days for delivery.

If you do not have a direct account with Nexperia our network of global and regional distributors is available and equipped to support you with Nexperia samples.

How does it work?

The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
