SN74AVCB324245 32-BIT DUAL-SUPPLY BUS TRANSCEIVER

ORDERING INFORMATION This 32-bit noninverting bus transceiver uses two separate configurable power-supply rails. The A port is designed to track VCCA. VCCA accepts any supply voltage from 1.4 V to 3.6 V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.4 V to 3.6 V. This allows for universal low-voltage bidirectional translation b.

Features

• Member of the Texas Instruments Widebus+™ Family
• DOC™ Circuitry Dynamically Changes Output Impedance, Resulting in Noise Reduction Without Speed Degradation
• Dynamic Drive Capability Is Equivalent to Standard Outputs With IOH and IOL of
  – ±24 mA at 3-V VCC
  – ±15 mA at 2.3-V VCC
  – ±9 mA at 1.65-V VCC
  – ±6 mA at 1.4-V VCC
• Control Inputs VIH/VIL Levels Are Referenced to VCCB Voltage
• If Either VCC Input Is at GND, Both Ports Are in the High-Impedance State
• Inputs/Outputs Can Tolerate up to 4.6 V, Which Allows Mixed-Voltage-Mode Data Communications
• Ioff Supports Partial-Power-Down Mod.
