FXL4245
Low Voltage Dual Supply 8-Bit Signal Translator
with Configurable Voltage Supplies
and Signal Levels and 3-STATE Outputs
General Description
The FXL4245 is a configurable dual-voltage-supply transla-
tor designed for bi-directional voltage translation of signals
between two voltage 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. Both ports are designed to accept supply voltage lev-
els from 1.1V to 3.6V. 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.
The device also contains power down control circuits that
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 OE input, when HIGH,
disables both the A and B Ports by placing them in a
3-STATE condition. The FXL4245 is designed so that the
control pins (T/R and OE) are supplied by VCCA.
Features
s Bi-directional interface between any 2 levels from
1.1V to 3.6V
s Fully configurable, inputs track VCC level
s Non-preferential power-up sequencing; either VCC may
be powered-up first
s Outputs remain in 3-STATE until active VCC level is
reached
s Outputs switch to 3-STATE if either VCC is at GND
s Power-off protection
s Control inputs (T/R, OE) levels are referenced to VCCA
voltage
s Packaged in 24-terminal MLP
s 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)
