General Description

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 without a control pin.

Key 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 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.
