GTL2002DP/DG,118

Translators, Level Shifters Overview

The GTL2002DP is a Gunning Transceiver Logic - Transceiver Voltage Clamp (GTL-TVC) device manufactured by NXP USA Inc. It provides bidirectional voltage translation between logic levels ranging from 1.0 V to 5.0 V without requiring a direction pin. The component contains two NMOS pass transistors with a common gate and a reference transistor, enabling seamless translation between higher and lower voltages. It operates within an ambient temperature range of -40 °C to +85 °C and is housed in a TSSOP8 plastic thin shrink small outline package.

Translators, Level Shifters Feature Summary

• Bidirectional voltage translation capability between 1.0 V and 5.0 V buses without the need for a direction control pin
• Low ON-state resistance between input and output pins ensuring minimal signal degradation
• Supports hot insertion and requires no external power supply while preventing latch-up conditions
• High electrostatic discharge protection exceeding specified HBM and CDM standards

Translators, Level Shifters Applications

• Bidirectional low voltage processor I2C-bus port translation to standard 3.3 V or 5.0 V signal levels
• Translation between GTL/GTL+ logic levels and LVTTL/TTL signal levels
• Applications requiring unidirectional or bidirectional voltage level shifting between any voltages within the 1.0 V to 5.0 V range

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix to confirm the TSSOP8 package type and reel packing method. Confirm the operating temperature range matches system requirements. Check for RoHS compliance status and ensure the component availability aligns with production schedules. Validate pin configuration against PCB layout specifications before procurement.

Translators, Level Shifters Selection Notes

Select this component when interfacing systems with varying voltage domains between 1.0 V and 5.0 V. Ensure the application benefits from the absence of direction pins and supports open-drain configurations for bidirectional data lines. Verify that the pull-up resistor values are calculated correctly to maintain acceptable pass voltage levels during operation.

Translators, Level Shifters Part Context

This part belongs to the GTL2002 family of 2-bit bidirectional low voltage translators. It shares functional characteristics with variants such as GTL2002D, GTL2002DC, and GTL2002GM, differing primarily in package style and manufacturing lot identifiers. The device is designed to replace discrete transistor solutions by providing symmetrical fabrication and easier board layout.

Translators, Level Shifters Replacement Considerations

Direct substitutes include GTL2002D, GTL2002DC, and GTL2002GM. These alternatives offer identical electrical performance but utilize different packages such as SO8, VSSOP8, or XQFN8. Verify footprint compatibility and pinout alignment when considering these replacements.
