ST2329

2-bit dual supply level translator

without direction control pin

Features

■ 90 Mbps (max) data rate when driven by a

totem pole driver

■ I2C level translation

■ UART level translation

QFN10L (1.8 x 1.4 mm)

Description

The ST2329 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 ST2329 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 ST2329 supports power down mode when

VCC is grounded/floating and the device is

disabled via the OE pin.
