ST2349A - 4-bit dual supply level translator

General 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.

Key Features

  • 90 Mbps (max) data rate when driven by a totem pole driver 8 Mbps (max) data rate when driven by an open drain pole driver Bi-directional 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 Power down mode feature.
  • when either supply is off, all I/Os are in high impedance Low quiescent current (max 24 µA) Able to be driven by totem pole and open d.
