ST2129 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. Its architecture allows bidirectional level translation without a control pin.
ST2129 Key Features
- 42 MHz: 84 Mbps (max) data rate at VL = 1.8 V, VCC = 3.3 V

- 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
