Manufacturer: ON Semiconductor
Catalog
Low Voltage Dual Supply 4-Bit Signal Translator with Configurable Voltage Supplies and Signal Levels and 3-STATE Outputs and Independent Direction Controls
Key Features
• Bi-directional interface between any 2 levels from 1.1V to 3.6V
• Fully configurable: Inputs track VCClevel
• Non-preferential power-up sequencing; either VCCmay be powered-up first
• Outputs remain in 3-STATE until active VCClevel is reached
• Outputs switch to 3-STATE if either VCCis at GND
• Power-off protection
• Control inputs (T/R n, OE) levels are referenced to VCCAvoltage
• Packaged in 16-terminal DQFN (2.5mm x 3.5mm)and 16-terminal MicroMLP (1.8mm x 2.6mm)
• ESD Protection 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)
Description
AI
The FXL4TD245 is a configurable 4-bit 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 VCCAlevel, and the B Port tracks the VCCBlevel. 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 VCCto be powered-up first. Internal power down control circuits place the device in 3-STATE if either VCCis removed. The Transmit/Receive (T/<span style="text-decoration: overline">R</span>) input determines the direction of data flow through the device. The <span style="text-decoration: overline">OE</span> input, when HIGH, disables both the A and B Ports by placing them in a 3-STATE condition. The FXL4TD245 is designed so that the control pins (T/<span style="text-decoration: overline">R</span> and <span style="text-decoration: overline">OE</span>) are supplied by VCCA.
