STMicroelectronics ST2349I
The ST2349I device is a 4-bit dual supply level translator which provides the level shifting capability to allow data transfer in a multi-voltage system. It utilizes transmission gate-based design that allows bidirectional level translation without a control pin. The ST2349I device 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/PLDs and higher voltage systems.| Part No. | ST2349I |

FEATURES
● 18 Mbps (max.) data rate when driven by a totem pole driver● 6.8 Mbps (max.) data rate when driven by an open drain pole driver
● Bidirectional level translation without direction control pin
● Wide VL voltage range of 1.65 to 3.6 V
● Wide VCC voltage range of 1.80 to 5.5 V
● Integrated 10 k pull-up on VCC and VL sides
● Power-down mode feature – when either supply is off, all I/Os are in high impedance
● Low quiescent current (max. 8 µA)
● Able to be driven by totem pole and open drain drivers
● 5.5 V tolerant enable pin
● ESD performance on all pins: ±2 kV HBM
● Small package and footprint QFN16 (2.6 x 1.8 mm) package
APPLICATIONS
● Low voltage system level translation● Mobile phones and other mobile devices
● I2C level translation
● UART level translation
DESCRIPTION
Externally applied voltages, VCC and VL, set the logic levels on either side of the device. This device has a tri-state output mode which can be used to disable all I/Os. The ST2349I device supports power-down mode when VCC is grounded/floating and the device is disabled via the OE pin.
