Description
The ST2129 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, V_CC and V_L, set the logic levels
on either side of the device. Its architecture allows
bidirectional level translation without a control pin.
The ST2129 accepts V_L from 1.65 to 3.6 V and
V_CC from 1.65 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 ST2129 supports power-down mode when
V_CC is grounded/floating or when the device is
disabled via the OE pin.
