Overview
The GTL2002DP/DG,118, produced by NXP USA Inc., is a 2-bit bidirectional low voltage translator. It 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. This device enables seamless voltage level translation between various voltage levels, ranging from 1.0 V to 5.0 V, without the need for a direction pin. It is particularly useful in applications requiring interface between different voltage domains, such as GTL, GTL+, LVTTL/TTL, and 5 V CMOS levels.
