GTL2000DGG,118

Translators, Level Shifters Overview

The GTL2000DGG,118 is a 22-bit bi-directional low voltage translator manufactured by NXP USA Inc. It provides high-speed voltage translation between 1.0 V and 5.0 V busses without requiring direction pins. The device features a low 6.5 Ω RDSON resistance between input and output pins (Sn/Dn). It supports hot insertion, has no power supply requirement, and will not latch up. Inputs are 5 V tolerant with low stand-by current. ESD protection exceeds 2000 V HBM per JESD22-A114, 200 V MM per JESD22-A115, and 1000 V per JESD22-C101. It 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 6.5 Ω RDSON resistance between input and output pins for minimal propagation delay
• Supports hot insertion and operates without a power supply without latching up
• Includes excellent ESD protection exceeding 2000 V HBM

Translators, Level Shifters Applications

• Bi-directional or unidirectional voltage level translation from any voltage between 1.0 V to 5.0 V to any voltage between 1.0 V to 5.0 V
• Translation of bi-directional low voltage processor I2C port signals to normal 3.3 V and/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 matches the required package type, as the GTL2000 series includes variants like GTL2000DL for SSOP48 and GTL2000DGG for TSSOP48. Confirm temperature range requirements against the -40 to +85 °C rating. Ensure pull-up resistor values align with the specified current limits to maintain proper pass voltage characteristics during operation.

Translators, Level Shifters Selection Notes

Select this component when interfacing between different logic families such as GTL, GTL+, LVTTL, TTL, and 5 V CMOS. It is suitable for applications requiring seamless translation between user-selected voltages within the 1.0 V to 5.0 V range. The flow-through pinout facilitates easier printed circuit board trace routing compared to discrete solutions.

Translators, Level Shifters Part Context

The GTL2000 belongs to the Gunning Transceiver Logic — Transceiver Voltage Clamps (GTL-TVC) family. It utilizes 22 NMOS pass transistors with a common gate and a reference transistor to achieve symmetrical fabrication. This design ensures minimal deviation in voltage or propagation delay across outputs, offering advantages over discrete transistor voltage translation solutions.

Translators, Level Shifters Replacement Considerations

The GTL2002 serves as a lower-pin-count alternative with 2 bits instead of 22. For higher bit counts, the GTL2010 offers 10 bits. Verify that the replacement part number matches the required package and temperature range specifications.
