ST1G3236DTR

Translators, Level Shifters Overview

The ST1G3236DTR is a dual-supply CMOS 1-bit bus transceiver designed for level translation between mixed-voltage buses. It supports VCCA and VCCB operating ranges from 1.2V to 3.6V, with VCCB constrained to be lower than or equal to VCCA. The device features balanced propagation delays of up to 4.0ns maximum at 85°C and includes power-down protection on all inputs and outputs. A key characteristic is the integration of a 26Ω series resistor on the A-side outputs. Quiescent supply current is limited to 5μA maximum at 85°C.

Translators, Level Shifters Feature Summary

• Integrated 26Ω series resistor on A-side outputs
• Power-down protection on inputs and outputs
• Balanced propagation delays (tPLH ≈ tPHL)
• Low quiescent power dissipation

Translators, Level Shifters Applications

• Interface between 3.3V and 2.5V buses
• Interface between 3.3V and 1.2V buses
• Mixed supply systems requiring asynchronous communication

Translators, Level Shifters Procurement Notes

Verify that the specific DFN6L package variant matches the required footprint dimensions. Confirm that the application environment does not exceed the absolute maximum ratings for input voltage or power dissipation. Ensure that the DIR pin logic levels are compatible with the VCCB supply rail as specified in the recommended operating conditions.

Translators, Level Shifters Selection Notes

Select this component when interfacing two distinct voltage domains where only a single bidirectional data line is required. The integrated series resistor simplifies design by reducing signal reflections without external components. Verify that the target system operates within the 1.2V to 3.6V range and that the direction control logic aligns with the DIR pin tracking requirements relative to VCCB.

Translators, Level Shifters Part Context

This device belongs to the ST1G3xxx family of dual-supply bus transceivers manufactured using sub-micron silicon gate C2MOS technology. It is specifically engineered to facilitate high-speed, low-power communication between digital buses operating at different voltage levels, such as legacy 3.3V systems and modern low-voltage 1.2V or 2.5V peripherals.

Translators, Level Shifters Replacement Considerations

Check datasheets for other STMicroelectronics dual-supply transceivers like the ST1G3237 or ST1G3238 to verify pin compatibility and electrical parameter alignment before substitution.
