8 mm) 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 tristate 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.
