ST2329 Supplementary notes
3 Supplementary notes
3.1 Driver requirement
The ST2329 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/O
ensure that the driver is able to sink the required amount of current. For example, if the
settings are V
=5.5V, VL= 4.3 V and the pull-up resistor is 10 kΩ, then the driver must be
CC
able to sink at least (5.5 V/10 kΩ) + (4.3 V /10 kΩ)
requirements of the ST2329.
3.2 Load driving capability
To support the open drain system, the one-shot transistor is turned on only during state
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.
During the translation from V
side to VL side, the oscillation might be triggered when the
CC
signal is reflected back as a glitch. This is caused by the architecture of the device (autodirection).
When using the ST2329, care need to be taken in the PCB data-track design and output
loading. It is recommended that the load is less than 25 pf.
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 V
(device is disabled). There will be no current consumption in V
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. Refer also to the STMicroelectronics SURE

1. The data rate is guaranteed based on the condition that the output I/O signal rise/fall time is less than 15% of the input I/O
signal period; the input I/O signal is at 50% duty cycle and the output I/O signal duty cycle deviation not less than 30%.

Package mechanical data ST2329
7 Package mechanical data
In order to meet environmental requirements, ST offers these devices in ECOPACK®
packages. These packages have a Lead-free second level interconnect. The category of
second level interconnect is marked on the package and on the inner box label, in
compliance with JEDEC Standard JESD97. The maximum ratings related to soldering
conditions are also marked on the inner box label. ECOPACK is an ST trademark.
ECOPACK specifications are available at: www.st.com.
