Overview
The GTL2002D,112 is a 2-bit bidirectional low voltage translator produced by NXP USA Inc. It belongs to 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 is particularly useful for applications requiring voltage level translation between different voltage buses without the need for a direction pin.
