GTL2002DP General Description

The Gunning Transceiver Logic - Transceiver Voltage Clamps(GTLTVC) provide high-speed voltage translation with lowON-state resistance and minimal propagation delay. The GTL2002provides 2 NMOS pass transistors (Sn and Dn) with a common gate(G_REF) and a reference transistor (SREF and D_REF). The deviceallows bi-directional voltage translations between 1.0 V and 5.0 Vwithout use of a direction pin.

When the Sn or Dn port is LOW the clamp is in the ON-state and alow resistance connection exists between the Sn and Dn ports.Assuming the higher voltage is on the Dn port, when the Dn port ishigh, the voltage on the Sn port is limited to the voltage set by thereference transistor (S_REF). When the Sn port is high, the Dn port ispulled to V_CC by the pull up resistors. This functionality allows aseamless translation between higher and lower voltages selected bythe user, without the need for directional control.

All transistors have the same electrical characteristics and there isminimal deviation from one output to another in voltage orpropagation delay. This is a benefit over discrete transistor voltagetranslation solutions, since the fabrication of the transistors issymmetrical. Because all transistors in the device are identical,SREF and DREF can be located on any of the other two matchedSn/Dn transistors, allowing for easier board layout. The translator'stransistors provides excellent ESD protection to lower voltagedevices and at the same time protect less ESD resistant devices.

GTL2002DP Typical Application

• Any application that requires bi-directional or unidirectional
   voltage level translation from any voltage between 1.0 V and 5.0 V
   to any voltage between 1.0 V and 5.0 V

• The open drain construction with no direction pin is ideal for
   bi-directional low voltage (e.g., 1.0 V, 1.2 V, 1.5 V, or 1.8 V)processor I
   2C port translation to the normal 3.3 V or 5.0 V I2C-bus
   signal levels or GTL/GTL+ translation to LVTTL/TTL signal levels.
