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.
production data
QFN16 (2.6 x 1.8 mm)
The ST2149 accepts VL from 1.65 to 3.6 V and VCC from 1.65 to 5.5 V, making it ideal for data transfer between low-voltage
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.
