Overview
The GTL2002DP,118 is a 2-bit bidirectional low-voltage translator produced by NXP USA Inc. This device is part of the Gunning Transceiver Logic - Transceiver Voltage Clamps (GTL-TVC) family, designed to provide high-speed voltage translation with low ON-state resistance and minimal propagation delay. It features 2 NMOS pass transistors (Sn and Dn) with a common gate (GREF) and reference transistors (SREF and DREF), enabling bidirectional voltage translations between 1.0 V and 5.0 V without the need for a direction pin. Although the GTL2002DP is not recommended for new designs and has been replaced by the NVT2002DP, it remains a significant component in existing systems.
