GTL2010PW/G,118

Translators, Level Shifters Overview

The GTL2010PW/G,118 is a Gunning Transceiver Logic - Transceiver Voltage Clamp (GTL-TVC) providing high-speed voltage translation with low ON-state resistance and minimal propagation delay. It features 10 NMOS pass transistors (Sn and Dn) with a common gate (GREF) and a reference transistor (SREF and DREF). The device allows bidirectional voltage translations between 1.0 V and 5.0 V without requiring a direction pin. It supports hot insertion, has no power supply requirement to prevent latch-up, and offers 5 V tolerant inputs with low standby current.

Translators, Level Shifters Feature Summary

• Bidirectional voltage translation capability between 1.0 V and 5.0 V buses without the need for a direction pin
• Low ON-state resistance of 6.5 Ω between input and output pins ensuring minimal signal degradation
• Supports hot insertion and operates without a dedicated power supply to avoid latch-up conditions
• Flow-through pinout design facilitates ease of printed-circuit board trace routing

Translators, Level Shifters Applications

• Bidirectional or unidirectional voltage level translation from any voltage within the 1.0 V to 5.0 V range to another voltage in the same range
• Translation of low voltage processor I2C-bus ports (e.g., 1.0 V, 1.2 V, 1.5 V, or 1.8 V) to standard 3.3 V and/or 5.0 V I2C-bus signal levels
• Direct interface translation between GTL/GTL+ logic levels and LVTTL/TTL signal levels

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix matches the required package type, as the GTL2010 series includes both TSSOP24 and HVQFN24 variants. Confirm that the temperature range aligns with system requirements, as the standard PW variant operates from -40 °C to +85 °C. Ensure compatibility with the intended voltage levels and check for any specific ESD protection needs relative to the connected components.

Translators, Level Shifters Selection Notes

Select this component when designing interfaces between mixed-voltage logic families such as GTL, LVTTL, and CMOS. It is particularly suitable for applications requiring seamless bidirectional data transfer without complex directional control logic. Consider the flow-through pinout for simplified PCB layout and ensure pull-up resistor values are calculated correctly to maintain optimal pass voltage characteristics.

Translators, Level Shifters Part Context

The GTL2010 belongs to NXP's Gunning Transceiver Logic - Transceiver Voltage Clamps family, designed specifically for high-speed voltage translation. Unlike discrete transistor solutions, it offers symmetrical fabrication for consistent electrical characteristics across all channels. This integration simplifies board layout by allowing the reference transistor to be mapped onto any matched port, enhancing design flexibility for multi-channel translation tasks.

Translators, Level Shifters Replacement Considerations

The GTL2000 serves as a higher-density alternative offering 22-bit bidirectional translation. When replacing the GTL2010, verify that the increased channel count does not impact board space constraints and confirm that the pinout differences are accommodated in the existing design.

Translators, Level Shifters FAQ

Does the GTL2010 require an external power supply to function?

No, the device does not require a power supply and will not latch up, making it suitable for applications where power sequencing is critical.

How is bidirectional translation achieved without a direction pin?

Bidirectional translation is achieved through an open-drain construction where the GREF and DREF pins are tied together and pulled high, allowing the device to automatically handle voltage shifts in either direction.
