ST2329
2-bit dual supply level translator
without control pin
Data Brief
QFN10L (1.8mm x 1.4mm)
Description
ST2329 is a level translator providing level shifting
necessary to allow data transfer in a multi-voltage
system. Externally applied voltages, V_CC and V_L,
set the logic levels on either side of the device. It
utilizes transmission gate based design that
allows bidirectional level translation without
control pin.
The ST2329 accepts VL from 1.65V to 3.6V and
V_CC from 1.80V to 5.5V, making it ideal for data
transfer between low-voltage ASICs /PLD and
higher voltage system. This device has three-
state output mode that disables all I/Os.
ST2329 supports power-down mode at either of
its supply (V_L or V_CC) where it will disable all I/Os
when one of the supply is off. This feature will
protect the device from current backflow through
the device.
