Description
The ST2349A is a 4-bit dual supply level
translator which provides the level shifting
capability to allow data transfer in a multi-voltage
system. Externally applied voltages, VCC and VL,
set the logic levels on either side of the device. It
utilizes transmission gate-based design that
allows bi-directional level translation without a
control pin.
The ST2349A accepts a VL from 1.65 to 3.6 V
and VCC from 1.80 to 5.5 V, making it ideal for
data transfer between low-voltage ASICs/PLD
and higher voltage systems. This device has a tri-
state output mode which can be used to disable
all I/Os.
The ST2349A supports power down mode when
VCC is grounded/floating and the device is
disabled via the OE pin.

3 Supplementary notes
3.1 Driver requirement
The ST2349A may be driven by an open drain or totem pole driver and the nature of the
device’s output is “open drain”. It must not be used to drive a pull-down resistor since the
impedance of the output at HIGH state depends on the pull-up resistor placed at the I/Os.
As the device has pull-up resistors on both the I/OVCC and I/OVL ports, the user needs to
ensure that the driver is able to sink the required amount of current. For example, if the
settings are VCC =5.5V, V
L= 4.3 V and the pull-up resistor is 10 kΩ, then the driver must be
able to sink at least (5.5 V/10 kΩ) + (4.3 V/10 kΩ)=1 mA and still meet the VIL
requirements of the ST2349A.
3.2 Load driving capability
To support the open drain system, the one-shot transistor is turned on only during high
transition at the output side. When it drives a high state, after the one-shot transistor is
turned off, only the pull-up resistor is able to maintain the state. In this case, the resistive
load is not recommended.
3.3 Power off feature
In some applications where it might be required to turn off one of the power supplies
powering up the level translator, the user may turn off the VCC only when the OE pin is low
(device is disabled). There will be no current consumption in VL due to floating gates or
other causes, and the I/Os are in a high-impedance state in this mode.

Stressing the device above the rating listed in the “Absolute maximum ratings” table may
cause permanent damage to the device. These are stress ratings only, and operation of the
device at these or any other conditions above those indicated in the operating sections of
this specification is not implied. Exposure to absolute maximum rating conditions for
extended periods may affect device reliability.
