Product Introduction

Overview

The SN74AVC8T245RHLR is an 8-bit, dual-supply, noninverting bus transceiver produced by Texas Instruments. This device is designed for asynchronous communication between data buses and supports bidirectional voltage-level translation between various low-voltage nodes. It operates with two separate configurable power-supply rails, allowing each port to function over a wide voltage range from 1.2 V to 3.6 V. The SN74AVC8T245RHLR is optimized for use in systems requiring universal low-voltage translation and high-speed data transmission, making it suitable for a variety of applications including personal electronics, industrial, enterprise, and telecom sectors.

Key Features

  • Fully configurable dual-rail design allowing each port to operate over the full 1.4-V to 3.6-V power-supply range.
  • I/Os are 4.6-V tolerant.
  • Supports high-speed translation with data rates up to 320 Mbps when both VCCA and VCCB are ≥ 1.8 V.
  • Ioff supports partial power-down mode operation, preventing backflow current when the device is powered down.
  • VCC isolation feature – both ports are in the high-impedance state when either VCC input is at GND.
  • ESD protection exceeds JESD 22 standards.
  • Latch-up performance exceeds 100 mA per JESD 78, Class II.
  • Control inputs (DIR and OE) are supplied by VCCA.

Applications

  • Personal electronics
  • Industrial applications
  • Enterprise systems
  • Telecom equipment

Q & A

  1. What is the SN74AVC8T245RHLR used for?

    The SN74AVC8T245RHLR is used for asynchronous communication between data buses and supports bidirectional voltage-level translation between various low-voltage nodes.

  2. What is the operating voltage range for the SN74AVC8T245RHLR?

    The device operates with supply voltages ranging from 1.2 V to 3.6 V for both VCCA and VCCB.

  3. What are the maximum data rates supported by the SN74AVC8T245RHLR?

    The device supports maximum data rates of 170 Mbps when VCCA or VCCB is less than 1.8 V, and up to 320 Mbps when both VCCA and VCCB are 1.8 V or higher.

  4. Does the SN74AVC8T245RHLR have ESD protection?
  5. How does the Ioff feature work in the SN74AVC8T245RHLR?

    The Ioff feature supports partial power-down mode operation by disabling the I/O output circuits, preventing damaging current backflow when the device is powered down.

  6. What is the VCC isolation feature in the SN74AVC8T245RHLR?

    The VCC isolation feature allows both ports to be in the high-impedance state when either VCC input is at GND.

  7. Can the SN74AVC8T245RHLR be used in single-supply systems?
  8. What is the package type and pin count of the SN74AVC8T245RHLR?

    The device comes in a VQFN (RHL) package with 24 pins.

  9. What are the thermal characteristics of the SN74AVC8T245RHLR?

    The device has a junction-to-ambient thermal resistance (RθJA) of 36.8 °C/W for the VQFN (RHL) package.

  10. How do the control inputs (DIR and OE) work in the SN74AVC8T245RHLR?

    The control inputs (DIR and OE) are supplied by VCCA. The DIR input controls the direction of data transmission, and the OE input can disable the outputs to isolate the buses.
