SN74LVC1T45DCKT

The SN74LVC1T45DCKT is a single-bit non-inverting 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 to 5.5V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.65 to 5.5V. 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. It is designed so that the DIR input is powered by VCCA.

• 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, 4μA 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.
