1 / 21 page SN74AVC20T245 20BIT DUALSUPPLY BUS TRANSCEIVER WITH CONFIGURABLE VOLTAGE TRANSLATION AND 3STATE OUTPUTS SCES566F − MAY 2004 − REVISED APRIL 2005 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D Control Inputs VIH/VIL Levels are Referenced to VCCA Voltage D VCC Isolation Feature − If Either VCC Input Is at GND, Both Ports Are in the High-Impedance State D Overvoltage-Tolerant Inputs/Outputs Allow Mixed-Voltage-Mode Data Communications D Fully Configurable Dual-Rail Design Allows Each Port to Operate Over the Full 1.2-V to 3.6-V Power-Supply Range D Ioff Supports Partial-Power-Down Mode Operation D I/Os Are 4.6-V Tolerant D Max Data Rates − 380 Mbps (1.8-V to 3.3-V Translation) − 260 Mbps (< 1.8-V to 3.3-V Translation) − 260 Mbps (Translate to 2.5 V) − 210 Mbps (Translate to 1.8 V) − 120 Mbps (Translate to 1.5 V) − 100 Mbps (Translate to 1.2 V) D Latch-Up Performance Exceeds 100 mA Per JESD 78, Class II D ESD Protection Exceeds JESD 22 − 8000-V Human-Body Model (A114-A) − 200-V Machine Model (A115-A) − 1000-V Charged-Device Model (C101) description/ordering information This 20-bit noninverting bus transceiver uses two separate configurable power-supply rails. The SN74AVC20T245 is optimized to operate with VCCA/VCCB set at 1.4 V to 3.6 V. It is operational with VCCA/VCCB as low as 1.2 V. The A port is designed to track VCCA. VCCA accepts any supply voltage from 1.2 V to 3.6 V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.2 V to 3.6 V. This allows for universal low-voltage bidirectional translation between any of the 1.2-V, 1.5-V, 1.8-V, 2.5-V, and 3.3-V voltage nodes.
