Resumen del producto

The SN74LVC1T45DBVT is a single-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 5.5V. This allows for universal low-voltage bidirectional translation between any of the 1.8, 2.5, 3.3 and 5V voltage nodes. The SN74LVC1T45 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. The SN74LVC1T45DBVT 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
