ST2149 Overview
Key Specifications
Package: QFN
Mount Type: Surface Mount
Pins: 12
Operating Voltage: 1.8 V
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.
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
