●The SN74LVC2T45DCTT is a Dual-bit Non-inverting Bus Transceiver IC uses two separate configurable power-supply rails. The A port is designed to track VCCA. VCCA accepts any supply voltage from 1.65 to 5.5V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.65 to 5.5 V. This allows for universal low-voltage bidirectional translation between any of the 1.8, 2.5, 3.3 and 5V voltage nodes. It is designed for asynchronous communication between two data buses. The logic levels of the direction-control (DIR) input activate either the B-port outputs or the A-port outputs. The device transmits data from the A bus to the B bus when the B-port outputs are activated and from the B bus to the A bus when the A-port outputs are activated. The input circuitry on both A and B ports always is active and must have a logic HIGH or LOW level applied to prevent excess ICC and ICCZ.
● Fully configurable dual-rail design allows each port to operate over 1.65 to 5.5V power supply range
● VCC Isolation Feature, If Either VCC Input is at GND, Both Ports are in High-impedance State
● DIR Input Circuit Referenced to VCCA
● Low-power Consumption, 10µA Maximum ICC
● ±24mA Output Drive at 3.3V
● Ioff Supports Partial-power-down Mode Operation
● 420Mbps(3.3 to 5V Translation) 210Mbps(Translate to 3.3V), 75Mbps (Translate to 1.8V) max data rates
● Latch-up Performance Exceeds 100mA Per JESD 78, Class II
● Green Product, No Sb/Br
●Device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
