SN74AVCH20T245 20ĆBIT DUALĆSUPPLY BUS TRANSCEIVER WITH CONFIGURABLE VOLTAGE TRANSLATION AND 3ĆSTATE OUTPUTS
SCES567F − MAY 2004 − REVISED APRIL 2005
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 Bus Hold on Data Inputs Eliminates the
Need for External Pullup/Pulldown Resistors
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.
