Overview
The GTL2000DGG,512, produced by NXP USA Inc., is a 22-bit bi-directional low voltage translator. 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 allows for voltage level translation between various voltage levels, including 1.0 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5 V, making it suitable for interfacing with different logic levels such as GTL, GTL+, LVTTL/TTL, and 5 V CMOS.
