74AVCH16244DGG

16-bit buffer/line driver; 3.6 V tolerant; 3-state

The 74AVCH16244 is a 16-bit non-inverting buffer/line driver with 3-state outputs. The device can be used as four 4-bit buffers, two 8-bit buffers or one 16-bit buffer. The 3‑state outputs are controlled by the output enable inputs nOE. A HIGH on nOE causes the outputs to assume a high impedance OFF-state.

The 74AVCH16244 is designed to have an extremely fast propagation delay and a minimum amount of power consumption.

To ensure the high-impedance output state during power-up or power-down, nOE should be tied to VCC through a pull-up resistor (Live Insertion).

A dynamic controlled output (DCO) circuitry is implemented to support termination line drive during transient.

The 74AVCH16244 has active bus-hold circuitry to hold unused or floating data inputs at a valid logic level. This feature eliminates the need for external pull-up or pull-down resistors.

Features and benefits

  • Wide supply voltage range from 1.2 V to 3.6 V

  • CMOS low power consumption

  • Low inductance multiple VCC and GND pins for minimum noise and ground bounce

  • Input/output tolerant up to 3.6 V

  • Dynamic controlled output (DCO) circuit dynamically changes the output impedance, resulting in noise reduction without speed degradation

  • Bus hold on all data inputs

  • Supports Live Insertion

  • Complies with JEDEC standards:

    • JESD8-7 (1.2 V to 1.95 V)

    • JESD8-5 (1.8 V to 2.7 V)

    • JESD8-1A (2.7 V to 3.6 V)

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.
