SN74LVC2T45

SN74LVC2T45 SCES516M – DECEMBER 2003 – REVISED OCTOBER 2022 SN74LVC2T45 Dual-Bit Dual-Supply Bus Transceiver With Configurable Voltage Translation 1 Features Fully configurable dual-rail design allows each port to operate over the full 1.65-V to 5.5-V powersupply range VCC isolation feature – if either VCC input is at GND, both ports are in the high-impedance state DIR input circuit referenced to VCCA Low power consumption, 4-μA maximum ICC Available in the Texas Instruments NanoFree™ package ±24-mA output drive at 3.3 V Ioff supports Partial-Power-Down mode operation Maximum data rates: – 420 Mbps (3.3-V to 5-V translation) – 210 Mbps (translate to 3.3 V) – 140 Mbps (translate to 2.5 V) – 75 Mbps (translate to 1.8 V) Latch-up performance exceeds 100 mA per JESD 78, Class II ESD protection exceeds JESD 22 – 4000-V Human-Body Model (A114-A) – 200-V Machine Model (A115-A) – 1000-V Charged-Device Model (C101) 2 Applications Personal electronic Industrial Enterprise Telecom 5 DIR 2 A1 7 B1 3 Description This dual-bit noninverting bus transceiver uses two separate configurable power-supply rails. The A port is designed to track VCCA. VCCA accepts any supply voltage from 1.65 V to 5.5 V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.65 V to 5.5 V. This allows for universal low-voltage bidirectional translation between any of the 1.8-V, 2.5V, 3.3-V, and 5-V voltage nodes. The SN74LVC2T45 is designed for asynchronous co...
