HM5302 - 2-Bit Voltage Translator / Isolator

General Description

The HM5302 is a high-performance configurable dual-voltage-supply translator for bi-directional voltage translation over a wide range of input and output voltages levels.

The HM5302 also works in a push-pull environment.

Key Features

  • Bi-Directional Interface between Any Two Levels:1.65V to 5.5V.
  • No Direction Control Needed.
  • Internal 10K Pull-Up Resistors.
  • System GPIO Resources Not Required when OE tied to VCCA.
  • I2C-Bus Isolation.
  • A/B Port VOL = 175mV (Typical), VIL = 150mV, IOL = 6mA.
  • Open-Drain Inputs / Outputs.
  • Works in Push Pull Environment.
  • Accommodates Standard-Mode and Fast-Mode I2C-Bus Devices.
  • Supports I2C Clock Stretching & Multi-Master.

HM5302 Dual-Supply, 2-Bit Voltage Translator / Isolator for I2C Applications General Description The HM5302 is a high-performance configurable dual-voltage-supply translator for bi-directional voltage translation over a wide range of input and output voltages levels. The HM5302 also works in a push-pull environment. It is intended for use as a voltage translator between I2C-Bus compliant masters and slaves. Internal 10KΩ pull-up resistors are provided. The device is designed so the A port tracks the VCCA level and the B port tracks the VCCB level. This allows for bi-directional A/B-port voltage translation between any two levels from 1.65V to 5.5V. VCCA can equal VCCB from1.65V to 5.5V. Either VCC can be powered-up first.
