ST2149 4-bit dual supply level translator

The ST2149 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. Its architecture allows bi-directional level translation witho.

ST2149 Features

* 42 MHz: 84 Mbps (max.) data rate at VL = 1.8 V, VCC = 3.3 V

* Bi-directional level translation without direction control pin

* Wide voltage range (VCC ≥ VL):

* VL ranges from 1.65 to 3.6 V

* VCC ranges from VL to 5.5 V

* Power-down mode feature - when VCC supply is
