74LVC2245A

Octal transceiver with direction pin, 30 Ohm series termination resistors; 5 V tolerant input/output; 3-state

The 74LVC2245A is an 8-bit transceiver with 30 Ω termination resistors and 3-state outputs. The device features an output enable (OE) and send/receive (DIR) for direction control. A HIGH on OE causes the outputs to assume a high-impedance OFF-state. Inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of these devices as translators in mixed 3.3 V and 5 V environments.

Schmitt-trigger action at all inputs makes the circuit tolerant of slower input 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.

Features and benefits

  • Overvoltage tolerant inputs to 5.5 V

  • Wide supply voltage range from 1.2 V to 3.6 V

  • CMOS low-power consumption

  • Direct interface with TTL levels

  • IOFF circuitry provides partial Power-down mode operation

  • Integrated 30 Ω termination resistors

  • Complies with JEDEC standard:

    • JESD8-7A (1.65 V to 1.95 V)

    • JESD8-5A (2.3 V to 2.7 V)

    • JESD8-C/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 and -40 °C to +125 °C
