ST2129B - 2-bit dual supply level translator

General Description

The ST2129B device 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

  • 45 MHz: 90 Mbps (max. ) data rate  at VL = 1.8 V, VCC = 3.3 V.
  • Bi-directional level translation without direction control pin.
  • Wide voltage range (VL ≤ VCC):.
  • VL ranges from 1.65 to 3.6 V.
  • VCC ranges from VL to 5.5 V.
  • Totem pole driving.
  • 5.5 V tolerant Enable pin.
