GTL2000DL,518

Translators, Level Shifters Overview

The GTL2000DL,518 is a 22-bit bi-directional low voltage translator manufactured by NXP USA Inc. It operates within an ambient temperature range of -40 °C to +85 °C and utilizes a 48-pin Plastic SSOP package (SOT370-1). The device supports voltage level translation between busses operating at 1.0 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5 V. It provides a low on-state resistance of 6.5 Ω between input and output pins and features ESD protection exceeding 2000 V HBM per JESD22-A114.

Translators, Level Shifters Feature Summary

• Provides bi-directional voltage translation without requiring a direction pin
• Supports hot insertion with no power supply requirement and latch-up immunity
• Features flow-through pinout for ease of printed circuit board trace routing

Translators, Level Shifters Applications

• Bi-directional low voltage processor I2C port translation to normal 3.3 V or 5.0 V I2C bus signal levels
• GTL/GTL+ translation to LVTTL/TTL signal levels
• Applications requiring unidirectional voltage level translation from any voltage between 1.0 V and 5.0 V to any voltage between 1.0 V and 5.0 V

Translators, Level Shifters Procurement Notes

Verify the specific ordering code GTL2000DL against the datasheet to confirm the 48-pin Plastic SSOP package type. Ensure compatibility with the required temperature range of -40 to +85 °C. Confirm that the application design accounts for the recommended operating conditions, specifically maintaining VSREF at least 1.5 V lower than VDREF for optimal level shifting performance.

Translators, Level Shifters Selection Notes

Select this component when designing interfaces between mixed-voltage logic families such as GTL, GTL+, LVTTL, TTL, and 5 V CMOS. The device is suitable for applications needing seamless translation between higher and lower voltages without directional control logic. Consider the 22-bit width and the specific package constraints when evaluating board layout requirements.

Translators, Level Shifters Part Context

The GTL2000 belongs to the Gunning Transceiver Logic — Transceiver Voltage Clamps (GTL-TVC) family. This family provides high-speed voltage translation with low ON-state resistance and minimal propagation delay. The device integrates 22 NMOS pass transistors with a common gate and a reference transistor to facilitate the translation process.
