tm November 2006 ©2005 Fairchild Semiconductor Corporation www.fairchildsemi.com FXL2TD245 Rev. 1.0.4 1 FXL2TD245 Low Voltage Dual Supply 2-Bit Signal Translator with Configurable Voltage Supplies and Signal Levels and 3-STATE Outputs and Independent Direction Controls General Description The FXL2TD245 is a configurable dual-voltage-supply translator designed for both uni-directional and bi-direc- tional 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 volt- age 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 inputs independently determine the direction of data through each of the two bits. The OE input, when HIGH, disables both the A and B Ports by placing them in a 3-STATE condition. The FXL2TD245 is designed so that the control pins (T/R and OE) are supplied by VCCA. Features ■ 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 ■ Control inputs (T/Rn, OE) levels are referenced to VCCA voltage ■ Packaged in the Chipscale MicroPak10 (1.6mm x 2.1mm) ■ 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) Ordering Information Pb-Free package per JEDEC J-STD-020B.
