Low Voltage 1-Bit Bi-directional Level Translator with Configurable Voltage Supplies and Bushold Data Inputs (Advance Information)

Active

Overview

The FXLH1T45 is a single bit configurable dual-voltage supply translator designed for both uni-directional and bi-directional voltage translation between two logic levels. The device allows translation between voltages as high as 3.6V to as low as 1.1V. The A port tracks the VCCA level, and the B port tracks the VCCB level. This allows for bi-directional voltage translation over a variety of voltage levels: 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V. The device remains in 3-STATE until both VCCS reach active levels allowing either VCC to be powered-up first. Internal power down control circuits place the device in 3-STATE if either VCC is removed. The Transmit/Receive (T/<span style="text-decoration: overline">R</span>) input determines the direction of data flow through the device. The FXLH1T45 is designed so that the control pin (T/<span style="text-decoration: overline">R</span>) is supplied by VCCA

  • This product is general usage and suitable for many different applications.

  • Bi-directional interface between any 2 levels from 1.1V to 3.6V
  • Fully configurable: Inputs track VCC level
  • Non-preferential power-up sequencing; either VCC may be powered-up first
  • Outputs remain in 3-STATE until active VCC level is reached
  • Outputs switch to 3-STATE if either VCC is at GND
  • Power off protection
  • Bushold on data inputs eliminates the need for external pull-up/pull-down resistors
  • Control input (T/R) levels are referenced to VCCA voltage
  • Packaged in the MicroPak 6 (1.0mm x 1.45mm)
  • ESD protections exceeds: – 4kV HBM ESD (per JESD22-A114 & Mil Std 883e 3015.7) – 8kV HBM I/O to GND ESD (per JESD22-A114 & Mil Std 883e 3015.7) – 1kV CDM ESD (per ESD STM 5.3) – 200V MM ESD (per JESD22-A115 & ESD STM5.2)
