SN74AVCAH164245 16-BIT DUAL-SUPPLY BUS TRANSCEIVER

ORDERING INFORMATION This 16-bit (dual-octal) 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 .

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 2.5-V VCC
• Control Inputs VIH/VIL Levels Are Referenced to VCCA Voltage
• If Either VCC Input Is at GND, Both Ports Are in the High-Impedance State
• Overvoltage-Tolerant Inputs/Outputs Allow Mixed-Voltage-Mode Data Communications
• Ioff Supports Partial-Power-Down Mode Operation
• Fully Configurable Dual-Rail Design Allows Each Port to Operate .
