GTL2000DGG,112

Translators, Level Shifters Overview

The GTL2000DGG,112 is a 22-bit bi-directional low voltage translator manufactured by NXP USA Inc. It provides high-speed voltage translation between logic levels ranging from 1.0 V to 5.0 V without requiring direction control pins. The device features 22 NMOS pass transistors with a common gate and a reference transistor, enabling seamless translation between higher and lower voltages. It supports hot insertion, has no power supply requirement for operation, and offers 5 V tolerant inputs. The component is available in SSOP48 and TSSOP48 packages.

Translators, Level Shifters Feature Summary

• Provides bi-directional voltage translation between 1.0 V and 5.0 V busses without direction pins
• Features low on-state resistance between input and output pins
• Supports hot insertion and will not latch up without a power supply
• Includes ESD protection exceeding specified HBM and MM standards

Translators, Level Shifters Applications

• Bi-directional or unidirectional voltage level translation between any voltages within the 1.0 V to 5.0 V range
• Translation of low voltage processor I2C ports (e.g., 1.0 V to 1.8 V) to standard 3.3 V or 5.0 V I2C bus signal levels
• GTL/GTL+ translation to LVTTL/TTL signal levels

Translators, Level Shifters Procurement Notes

Verify the specific ordering code suffix against official documentation to confirm package type and temperature range. Confirm that the GTLREF pin configuration matches the intended application circuit requirements. Ensure compatibility with existing board layouts due to flow-through pinout design. Check for updated datasheets as product data may supersede previous versions.

Translators, Level Shifters Selection Notes

Select this component when bi-directional translation between multiple voltage domains within the 1.0 V to 5.0 V range is required without directional control. It is suitable for applications needing low on-resistance and minimal propagation delay. Consider the flow-through pinout for easier PCB trace routing. Verify that the ESD protection ratings meet system requirements.

Translators, Level Shifters Part Context

The GTL2000 series belongs to the Gunning Transceiver Logic — Transceiver Voltage Clamps (GTL-TVC) family. These devices are designed for high-speed voltage translation with low ON-state resistance and minimal propagation delay. The GTL2000 specifically offers 22 channels, making it suitable for wide bus interfaces. It allows flexible board layout due to identical transistor characteristics across all channels.
