Overview

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.

  • 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 off, all I/Os are in high impedance
  • Totem pole driving
  • 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
