74LVT16646ADGG

74LVT16646ADGG End of life

3.3 V 16-bit bus transceiver; 3-state

The 74LVT16646A is a high-performance BiCMOS product designed for VCC operation at 3.3 V. This device is a 16-bit transceiver featuring non-inverting 3-state bus compatible outputs in both send and receive directions. The control function implementation minimizes external timing requirements. The device features an output enable (OE) input for easy cascading and a direction (DIR) input for direction control.

Data on bus A or bus B is clocked into the registers on the LOW-to-HIGH transition of the appropriate clock (CPAB or CPBA). The select control (SAB and SBA) inputs can multiplex stored and real-time (transparent mode data).

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.
