www.ti.com SN74AVCA164245 16-BIT DUAL-SUPPLY BUS TRANSCEIVER WITH CONFIGURABLE VOLTAGE TRANSLATION AND 3-STATE OUTPUTS SCES395B – JULY 2002 – REVISED OCTOBER 2005 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 Over the Full 1.4-V to 3.6-V Power-Supply Range Latch-Up Performance Exceeds 100 mA Per JESD 78, Class II ESD Protection Exceeds JESD 22 – 2000-V Human-Body Model (A114-A) – 200-V Machine Model (A115-A) – 1000-V Charged-Device Model (C101) DESCRIPTION/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 translation between any of the 1.5-V, 1.8-V, 2.5-V, and 3.3-V voltage nodes. The SN74AVCA164245 is designed ...
