Translators, Level Shifters datasheet and documents for ST2129QTR

ST2129QTR

Translators, Level Shifters Overview

The ST2129QTR is a 2-bit dual supply level translator manufactured by STMicroelectronics in a QFN10 package (1.8 x 1.4 mm). It supports bidirectional translation without direction control pins, with VL ranging from 1.65 to 3.6 V and VCC from 1.65 to 5.5 V. The device achieves data rates up to 86 Mbps at VCC = 4.5–5.5 V. Propagation delays range from 2.3 ns to 6.6 ns depending on voltage conditions. It features power-down mode for high-impedance I/Os when VCC is off, an enable pin tolerant to 5.5 V, and ±2 kV HBM ESD protection.

Translators, Level Shifters Feature Summary

Bidirectional level translation architecture operating without dedicated direction control pins
Power-down mode automatically places all I/Os in high impedance state when the VCC supply is removed
Totem-pole driving capability with a 5.5 V tolerant output enable pin

Translators, Level Shifters Applications

Low voltage system level translation between multi-voltage domains
Data transfer interfaces connecting low-voltage ASICs or PLDs to higher voltage systems
Mobile phones and other mobile devices requiring compact footprint solutions

Translators, Level Shifters Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm package integrity upon receipt as the QFN10 form factor requires careful handling during inspection. Ensure that the specific ordering suffix matches the required tape and reel packaging configuration for automated assembly processes.

Translators, Level Shifters Selection Notes

Select this component when designing circuits requiring bidirectional translation between dissimilar voltage domains without complex control logic. The absence of a direction pin simplifies board layout. Verify that the driver can source and sink sufficient current to maintain proper operation within the specified voltage ranges.

Translators, Level Shifters Part Context

This part belongs to the ST2129 series of dual supply level translators. It provides a compact solution for interfacing different logic families in mixed-voltage environments. The QFN10 package offers a small footprint suitable for space-constrained portable electronics and modern mobile communication hardware designs.
