FXLH1T45
Low Voltage 1-Bit Bi-directional Level Translator with
tm
Configurable Voltage Supplies and Bushold Data Inputs
Features
■ Bi-directional interface between any 2 levels from 1.1V
to 3.6V
www.DataSheet4U.c■omFully 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)
General Description
The FXLH1T45 is a single bit configurable dual-voltage
supply translator designed for both uni-directional and
bi-directional voltage translation between two logic lev-
els. 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.
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 direc-
tion of data flow through the device. The FXLH1T45 is
designed so that the control pin (T/R) is supplied by
VCCA.
