GTL2002GM,125

Translators, Level Shifters Overview

The GTL2002GM,125 is a 2-bit bidirectional low voltage translator manufactured by NXP USA Inc. It provides high-speed voltage translation with low ON-state resistance and minimal propagation delay. The device allows bidirectional voltage translations between 1.0 V and 5.0 V without the use of a direction pin. It features two NMOS pass transistors (Sn and Dn) with a common gate (GREF) and a reference transistor (SREF and DREF). The component operates within an ambient temperature range of -40 °C to +85 °C and is housed in an XQFN8 package.

Translators, Level Shifters Feature Summary

• Provides bidirectional voltage translation between 1.0 V and 5.0 V without requiring a direction pin
• Features low 6.5 Ω ON-state resistance for efficient signal transfer
• Supports hot insertion and does not require a power supply or latch up

Translators, Level Shifters Selection Notes

Select this component when designing circuits requiring seamless bidirectional voltage translation between varying logic levels within the 1.0 V to 5.0 V range. Ensure GREF is maintained at least 1.5 V higher than SREF for optimal operation. Consider the flow-through pinout for simplified PCB trace routing and verify that external pull-up resistors are sized correctly to limit current through the pass transistors.

Translators, Level Shifters Part Context

The GTL2002GM,125 belongs to the GTL-TVC family, which utilizes Gunning Transceiver Logic principles for voltage clamping. This series is designed to interface different logic families and voltage domains efficiently. The GM suffix specifically denotes the XQFN8 package variant, offering a compact solution for space-constrained applications compared to larger SO or TSSOP packages.
