GTL2002DP/S440,118

Translators, Level Shifters Overview

The GTL2002DP is a 2-bit bidirectional low voltage translator from NXP Semiconductors, housed in an 8-lead TSSOP package (SOT505-1). It provides high-speed voltage translation between 1.0 V and 5.0 V without requiring a direction pin. The device features two NMOS pass transistors with a common gate and a reference transistor, enabling seamless translation between user-selected voltages. It supports hot insertion, has no power supply requirement, and offers ESD protection exceeding 2000 V HBM.

Translators, Level Shifters Feature Summary

• Bidirectional voltage translation between 1.0 V and 5.0 V without direction pins
• Low ON-state resistance for minimal signal degradation
• Supports hot insertion and operates without a dedicated power supply
• High ESD protection capability for robust system reliability

Translators, Level Shifters Applications

• Bidirectional I2C bus port translation between low voltage processors and standard 3.3 V or 5.0 V levels
• GTL/GTL+ to LVTTL/TTL signal level translation
• Unidirectional voltage level translation between any voltages within the 1.0 V to 5.0 V range

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix matches the required package type and tape/reel configuration. Confirm ambient temperature operating range requirements align with the specified -40 °C to +85 °C limits. Ensure input/output voltage ratings do not exceed the absolute maximum values defined in the datasheet to prevent device damage.

Translators, Level Shifters Selection Notes

Select this component when designing interfaces requiring automatic direction sensing without external control logic. It is suitable for applications needing direct interface with GTL, GTL+, LVTTL, TTL, and 5 V CMOS levels. Consider the flow-through pinout for simplified PCB trace routing compared to discrete solutions.

Translators, Level Shifters Part Context

This part belongs to the GTL2002 family of Gunning Transceiver Logic - Transceiver Voltage Clamps. The DP suffix specifically denotes the TSSOP8 plastic thin shrink small outline package variant. Other family members include SO8, VSSOP8, and XQFN8 packages, offering flexibility for different board space and thermal constraints.

Translators, Level Shifters Replacement Considerations

Direct substitutes within the same package are GTL2002D (SO8) and GTL2002DC (VSSOP8), though physical footprint differences apply. For identical TSSOP8 form factor, verify availability of GTL2002DP variants with different reel packing options.
