GTL2002D,112

Translators, Level Shifters Overview

The GTL2002D,112 is a 2-bit bidirectional low voltage translator manufactured by NXP USA Inc. It utilizes Gunning Transceiver Logic - Transceiver Voltage Clamp (GTL-TVC) technology to provide high-speed voltage translation with minimal propagation delay and low ON-state resistance. The device contains two NMOS pass transistors with a common gate and a reference transistor, enabling seamless voltage level shifting between any levels from 1.0 V to 5.0 V without requiring a direction pin. It operates within an ambient temperature range of -40 °C to +85 °C and is housed in an SO8 plastic small outline package.

Translators, Level Shifters FAQ

Does the GTL2002D require a power supply to operate?

No, the device does not require an external power supply and will not latch up.

How is bidirectional translation achieved without a direction pin?

The device uses a clamping mechanism where the Sn port follows the Dn input LOW, and the Dn port is pulled up to VCC by external resistors, allowing seamless translation based on voltage levels.
