74AVCH16245

16-bit transceiver with direction pin; 3.6 V tolerant; 3-state

The 74AVCH16245 is a 16-bit transceiver featuring non-inverting 3-state bus compatible outputs in both send and receive directions. The device features two output enable inputs (nOE) for easy cascading and two send/receive inputs (nDIR) for direction control. Inputs nOE control the outputs so that the buses are effectively isolated. This device can be used as two 8-bit transceivers or one 16-bit transceiver.

The 74AVCH16245 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, tie pins nOE 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 74AVCH16245 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 to 3.6 V
  • 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)
  • CMOS low power consumption
  • Input/output tolerant up to 3.6 V
  • Dynamic Controlled Output (DCO) circuit dynamically changes output impedance, resulting in noise reduction without speed degradation
  • Low inductance multiple VCC and GND pins to minimize noise and ground bounce
  • Supports Live Insertion
  • All inputs have bus-hold.
