Product Introduction

Overview

The SN74LVCC3245ADWR is an 8-bit (octal) noninverting bus transceiver produced by Texas Instruments. This device is designed to facilitate bidirectional voltage translation between two separate supply rails, making it ideal for interfacing between different voltage systems. The A port operates at voltages from 2.3 V to 3.6 V, while the B port operates at voltages from 3 V to 5.5 V, enabling seamless translation between 3.3-V and 5-V systems, or between 2.5-V and 3.3-V systems.

Propagation Delay Time (tpd) VCCA = 2.5 V, VCCB = 3.3 V - 9.9 - ns
Power Dissipation Capacitance (Cpd) Outputs Enabled, CL = 50 pF, f = 10 MHz - 38 - pF
Package Types Available Packages - - - DB (SSOP), DW (SOIC), DBQ (SSOP), NS (SO), PW (TSSOP)

Key Features

  • Bidirectional Voltage Translator: Enables translation between different voltage levels on the A and B ports.
  • Dual Supply Rails: A port operates at 2.3 V to 3.6 V, and B port operates at 3 V to 5.5 V.
  • Control Inputs: VIH and VIL levels are referenced to VCCA voltage.
  • Latch-up Performance: Exceeds 250 mA per JESD 17.
  • ESD Protection: Exceeds 2000-V Human Body Model and 1000-V Charged-Device Model.
  • Output Enable (OE): Active low output enable input.
  • Direction Control (DIR): Input to control the direction of data flow.

Applications

  • Level Translation: Translating signals between different voltage levels.
  • USB and Interfacing: Used in USB and other interfacing applications where voltage translation is necessary.
  • Analog and Digital Applications: Suitable for both analog and digital systems requiring voltage translation.

Q & A

  1. What is the primary function of the SN74LVCC3245ADWR?

    The primary function is to act as a bidirectional voltage translator between two separate supply rails.

  2. What are the operating voltage ranges for the A and B ports?

    The A port operates from 2.3 V to 3.6 V, and the B port operates from 3 V to 5.5 V.

  3. What is the significance of the DIR input?

    The DIR input controls the direction of data flow between the A and B ports.

  4. What is the purpose of the OE input?

    The OE (Output Enable) input is active low and controls the output state of the transceiver.

  5. What level of ESD protection does the SN74LVCC3245ADWR offer?

    The device offers ESD protection exceeding 2000-V Human Body Model and 1000-V Charged-Device Model.

  6. What are the available package types for the SN74LVCC3245ADWR?

    The available packages include DB (SSOP), DW (SOIC), DBQ (SSOP), NS (SO), and PW (TSSOP).

  7. What is the typical propagation delay time for this device?

    The typical propagation delay time (tpd) is around 9.9 ns for VCCA = 2.5 V and VCCB = 3.3 V.

  8. What is the power dissipation capacitance for this device?

    The power dissipation capacitance (Cpd) is typically 38 pF when outputs are enabled, with CL = 50 pF and f = 10 MHz.

  9. In what temperature range can the SN74LVCC3245ADWR operate?

    The device can operate in a free-air temperature range from -40°C to 85°C.

  10. What are some common applications of the SN74LVCC3245ADWR?

    Common applications include level translation, USB, interfacing, and both analog and digital systems requiring voltage translation.
