FXLH1T45 Low Voltage 1-Bit Bi-directional Level Translator with Configurable Voltage Supplies and Bushold Data Inputs Features General Description ■ Bi-directional interface between any 2 levels from 1.1V 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. 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) tm 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/R) input determines the direction of data flow through the device. The FXLH1T45 is designed so that the control pin (T/R) is supplied by VCCA.

This benefit derives from the chip design. When either VCC is at 0V, outputs are in a HIGH-Impedance state. To ensure that bus contention, excessive currents, or oscillations do not occur, a proper power-up sequence is recommended.

Apply power to the T/R input (Logic HIGH for A-to-B operation; Logic LOW for B-to-A operation) and to the respective data inputs (A Port or B Port). This may occur at the same time as Step 1.

The enable time specifies the worst-case delay from the time the T/R pin is switched until a valid output signal is expected. For example, to change direction to B-to-A operation, the T/R pin is switched from HIGH-to-LOW. The enable time for this case is found by adding the disable time for T/R to B to the propagation delay for B to A. The formulas for calculating enable times are the following: tPZH (T/R to A) = tPLZ (T/R to B) + tPLH (B to A) tPZL (T/R to A) = tPHZ (T/R to B) + tPHL (B to A) tPZH (T/R to B) = tPLZ (T/R to A) + tPLH (A to B) tPZL (T/R to B) = tPHZ (T/R to A) + tPHL (A to B) Capacitance TA = +25°C Symbol Conditions Typical Units CIN Input Capacitance Control Pin (T/R) Parameter VCCA = VCCB = 3.3V, VI = 0V or VCCA/B 4.0 pF CI/O Input/Output Capacitance An, Bn Ports VCCA = VCCB = 3.3V, VI = 0V or VCCA/B 5.0 pF CPD Power Dissipation Capacitance VCCA = VCCB = 3.3V, VI = 0V or VCC, F = 10MHz 20.0 pF ©2006 Fairchild Semiconductor Corporation FXLH1T45 Rev. 1.0.4 www.fairchildsemi.com 7 FXLH1T45 Low Voltage 1-Bit Bi-directional Level Translator with Configurable Voltage Supplies and Bushold Data Inputs AC Electrical Characteristics (Continued) VCC OPEN Rtr1 TEST SIGNAL tPLH, tPHL tPHZ tPLZ GND VCC x 2 DUT CL RL Test Switch tPLH, tPHL OPEN tPLZ VCCO x 2 at VCCO = 3.3 ± 0.3V, 2.5V ± 0.2V, 1.8V ± 0.15V, 1.5V ± 0.1V, 1.2V ± 0.1V tPHZ GND Figure 1.
