SN74AVC2T45 Datasheet

Dual-Bit Dual-Supply Bus Transceiver With Configurable Voltage Translation And 3-State Outputs


This dual-bit noninverting bus transceiver uses two separate configurable power-supply rails. The A port is designed to track V CCA . V CCA accepts any supply voltage from 1.2 V to 3.6 V. The B port is designed to track V CCB . V CCB 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. SN74AVC2T45 Features &bull; Available in the Texas Instruments NanoFree&trade; Package&bull; Control Inputs VIH/VIL Levels Are Referenced to VCCA Voltage&bull; Fully Configurable Dual-Rail Design Allows Each Port to Operate Over the Full 1.2-V to 3.6-V Power-Supply Range&bull; I/Os Are 4.6-V Tolerant&bull; Ioff Supports Partial-Power-Down Mode Operation&bull; Max Data Rates &ndash; 500 Mbps (1.8-V to 3.3-V Translation) &ndash; 320 Mbps (<1.8-V to 3.3-V Translation) &ndash; 320 Mbps (Translate to 2.5 V or 1.8 V) &ndash; 280 Mbps (Translate to 1.5 V) &ndash; 240 Mbps (Translate to 1.2 V)&bull; Latch-Up Performance Exceeds 100 mA Per JESD 78, Class II&bull; ESD Protection Exceeds JESD 22 &ndash; 8000-V Human-Body Model (A114-A) &ndash; 200-V Machine Model (A115-A) &ndash; 1000-V Charged-Device Model (C101)
