onsemi | FXLH1T45L6X

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 3.6 V to as low as 1.1 V. 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: 1.2 V, 1.5V, 1.8V, 2.5 V, 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.

Features:

• Bi-directional interface between any 2 levels from 1.1 V to 3.6 V
• 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 (1.0 mm x 1.45mm)
• ESD protections exceeds: – 4 kV HBM ESD (per JESD22-A114 & Mil Std 883e 3015.7) – 8 kV HBM I/O to GND ESD (per JESD22-A114 & Mil Std 883e 3015.7) – 1kV CDM ESD (per ESD STM 5.3) – 200 V MM ESD (per JESD22-A115 & ESD STM5.2)
