ST2329A
2-bit dual supply level translator
without direction control pin
Preliminary Data
QFN10L (1.8 x 1.4 mm)
Description
The ST2329A is a 2-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 bidirectional level translation without a
control pin.
The ST2329A 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 ST2329A supports power down mode when
VCC is grounded/floating and the device is
disabled via the OE pin.
