GTL2003PW,112

Translators, Level Shifters Overview

The GTL2003PW,112 is an 8-bit bidirectional low voltage translator from NXP Semiconductors. It provides high-speed voltage translation with low ON-state resistance and minimal propagation delay. The device contains eight NMOS pass transistors (Sn and Dn) with a common gate (GREF) and a reference transistor (SREF and DREF). It allows bidirectional voltage translations between 0.8 V and 5.0 V without the use of a direction pin. Voltage translation below 0.8 V can be achieved when properly biased. The device supports hot insertion, has no power supply requirement for operation, and will not latch up. It features 5 V tolerant inputs and low standby current.

Translators, Level Shifters Feature Summary

• Provides bidirectional voltage translation between 0.8 V and 5.0 V buses without requiring a direction pin
• Features low ON-state resistance between input and output pins to ensure minimal signal degradation
• Supports hot insertion and operates without a dedicated power supply, preventing latch-up conditions
• Includes ESD protection exceeding specified Human Body Model and Charged Device Model thresholds

Translators, Level Shifters Applications

• Bidirectional or unidirectional voltage level translation between any voltages from 0.8 V to 5.0 V
• Translation of low voltage processor I2C-bus ports to standard 3.3 V or 5.0 V I2C-bus signal levels
• Level shifting between GTL/GTL+ logic families and LVTTL/TTL signal levels

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and environmental compliance. The GTL2003PW,112 designation corresponds to the TSSOP20 plastic thin shrink small outline package. Confirm that the temperature range meets the application requirements, as this variant is rated for -40 °C to +85 °C. Ensure compatibility with existing PCB footprints for the SOT360-1 package outline before finalizing procurement decisions.

Translators, Level Shifters Selection Notes

Select the GTL2003PW,112 when designing systems requiring seamless voltage translation between multiple logic families without directional control overhead. The device is suitable for applications needing to interface low-voltage processors with higher voltage peripherals like I2C buses. Consider the flow-through pinout for ease of printed-circuit board trace routing. Evaluate the need for external pull-up resistors based on the specific voltage levels and open-drain configurations of the connected devices.

Translators, Level Shifters Part Context

The GTL2003 is part of NXP's Gunning Transceiver Logic - Transceiver Voltage Clamps (GTL-TVC) family. This series is designed to provide high-speed voltage translation with low ON-state resistance. The GTL2003 specifically offers an 8-bit configuration, distinguishing it from other members of the family such as the 2-bit GTL2002 or the 10-bit GTL2010. It utilizes symmetrical transistor fabrication to minimize deviation in voltage or propagation delay between outputs.

Translators, Level Shifters Replacement Considerations

For direct replacements within the same functional category, consider the GTL2002 for 2-bit applications or the GTL2010 for 10-bit requirements. Verify package compatibility if substituting with the GTL2003BQ, which uses a DHVQFN20 package instead of the TSSOP20 found in the GTL2003PW. Ensure that the replacement part maintains the required bidirectional translation capabilities and voltage ranges.
