74ALVC16245; 74ALVCH16245

16-bit transceiver with direction pin; 3-state

The 74ALVC16245; 74ALVCH16245 is a 16-bit transceiver with 3-state outputs. The device can be used as two 8-bit transceivers or one 16-bit transceiver. The device features two output enables (1OE and 2OE) each controlling eight outputs, and two send/receive (1DIR and 2DIR) inputs for direction control. A HIGH on nOE causes the outputs to assume a high-impedance OFF-state.

Schmitt trigger action on all inputs makes the device tolerant of slow rise and fall times.

This device is fully specified for partial power down applications using IOFF. The IOFF circuitry disables the output, preventing the potentially damaging backflow current through the device when it is powered down.

The 74ALVCH16245 has active bus hold circuitry which is provided 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

  • MULTIBYTE™ flow-through standard pin-out architecture

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

  • Overvoltage tolerant inputs to 5.5 V(74ALVC16245 only)

  • Direct interface with TTL levels

  • IOFF circuitry provides partial Power-down mode operation

  • Bushold on all data inputs(74ALVCH16245 only)

  • Output drive capability 50 Ω transmission lines at 85 °C

  • Current drive ±24 mA at 3.0 V

  • Latch-up performance exceeds 2500 mA per JESD 78 Class II.A

  • Complies with JEDEC standards:

    • JESD8-7 (1.65 V to 1.95 V)

    • JESD8-5 (2.3 V to 2.7 V)

    • JESD8C/JESD36 (2.7 V to 3.6 V)

  • ESD protection:

    • HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V
    • CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V

  • Specified from -40 °C to +85 °C
