GTL2002D,118

Translators, Level Shifters Overview

The GTL2002D,118 is a Gunning Transceiver Logic - Transceiver Voltage Clamp (GTL-TVC) device manufactured by NXP USA Inc. It provides high-speed voltage translation with low ON-state resistance and minimal propagation delay. The component contains two NMOS pass transistors (Sn and Dn) with a common gate (GREF) and a reference transistor (SREF and DREF). It supports bidirectional voltage translations between 1.0 V and 5.0 V without requiring a direction pin. The device operates within an ambient temperature range of -40 °C to +85 °C and is housed in an SO8 plastic small outline package.

Translators, Level Shifters Feature Summary

• Provides bidirectional voltage translation between 1.0 V and 5.0 V buses without the need for a direction pin
• Features low ON-state resistance between input and output pins for high-speed performance
• Supports hot insertion and requires no power supply, preventing latch-up conditions
• Includes ESD protection exceeding specified HBM and CDM standards

Translators, Level Shifters Applications

• Bidirectional or unidirectional voltage level translation between any voltages from 1.0 V to 5.0 V
• Translation of low voltage processor I2C-bus ports to standard 3.3 V or 5.0 V I2C signal levels
• Translation of GTL/GTL+ signal levels to LVTTL/TTL signal levels

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix '118' corresponds to the reel packing method as defined in the manufacturer's ordering information table. Confirm that the SO8 package variant matches the required PCB footprint dimensions. Ensure compatibility with the specified operating temperature range and voltage limits during system integration.

Translators, Level Shifters Selection Notes

Select this component when bidirectional level shifting is required without directional control logic. The open-drain construction is suitable for applications where outputs are open-drain, eliminating the need for direction control mechanisms. Consider the flow-through pinout for simplified printed-circuit board trace routing compared to discrete transistor solutions.

Translators, Level Shifters Part Context

The GTL2002D belongs to the GTL2002 family of 2-bit bidirectional low voltage translators. It utilizes Gunning Transceiver Logic technology to achieve seamless translation between user-selected higher and lower voltages. The symmetrical fabrication of transistors allows for easier board layout and minimal deviation in voltage or propagation delay between outputs.
