FXL2TD245
Low Voltage Dual Supply 2-Bit Signal Translator with
tm
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)
