74AVCH16244

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)
