ST2129 - 2-bit dual supply level translator

General Description

The ST2129 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.

Key Features

  • 42 MHz: 84 Mbps (max) data rate at VL = 1.8 V, VCC = 3.3 V.
  • Bidirectional level translation without direction control pin.
  • Wide voltage range (VCC ≥ VL):.
  • VL ranges from 1.65 to 3.6 V.
  • VCC ranges from 1.65 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: QFN10 (1.8 x 1.4 mm) Appli.
