The A ports Package are designed to track VCCA and accepts any supply • VCC Isolation voltage from 1.2 V to 3.6 V. The B ports are designed • 2-Rail Design to track VCCB and accepts any supply voltage from 1.2 V to 3.6 V. This allows for universal low-voltage • I/Os Are 4.6 V Tolerant bidirectional translation and level-shifting between • Partial-Power-Down Mode Operation any of the 1.2-V, 1.5-V, 1.8-V, 2.5-V, and 3.3-V • Max Data Rates voltage nodes. – 500 Mbps (1.8 V to 3.3 V) The SN74AVC2T45 is designed for asynchronous – 320 Mbps (<1.8 V to 3.3 V ) communication between two data buses. The logic levels of the direction-control (DIR pin) input activate – 320 Mbps (Level-Shifting to 2.5 V or 1.8 V) either the B-port outputs or the A-port outputs. The – 280 Mbps (Level-Shifting to 1.5 V) device transmits data from the A bus to the B bus – 240 Mbps (Level-Shifting to 1.2 V) when the B-port outputs are activated and from the B bus to the A bus when the A-port outputs are • Latch-Up Performance Exceeds 100 mA Per activated. The input circuitry on both A and B ports JESD 78, Class II always is active and must have a logic HIGH or LOW • ESD Protection Exceeds JESD 22 level applied to prevent excess leakage current on the internal CMOS structure. 2 Applications Device Information(1) • Smartphones PART NUMBER PACKAGE BODY SIZE (NOM) • Servers SSOP (8) 2.95 mm × 2.80 mm • Desktop PCs and Notebooks SN74AVC2T45 VSSOP (8) 2.30 mm × 2.00 mm • Other Portable Devices DSBGA (8) 1.89 mm × 0.89 mm (1) For all available packages, see the orderable addendum at the end of the data sheet.
