描述 Description

The Gunning Transceiver Logic - Transceiver Voltage Clamps (GTL-TVC) provide high-speed voltage translation with low ON-state resistance and minimal propagation delay. The GTL2000 provides 22 NMOS pass transistors (Sn and Dn) with a common gate (GREF) and a reference transistor (SREF and DREF). The device allows bi-directional voltage translations between 1.0 V and 5.0 V without use of a direction pin.
When the Sn or Dn port is low the clamp is in the ON-state and a low resistance connection exists between the Sn and Dn ports. Assuming the higher voltage is on the Dn port, when the Dn port is high, the voltage on the Sn port is limited to the voltage set by the reference transistor (SREF). When the Sn port is high, the Dn port is pulled to VCC by the pull up resistors. This functionality allows a seamless translation between higher and lower voltages selected by the user, without the need for directional control.
All transistors have the same electrical characteristics and there is minimal deviation from one output to another in voltage or propagation delay. This is a benefit over discrete transistor voltage translation solutions, since the fabrication of the transistors is symmetrical. Because all transistors in the device are identical, SREF and DREF can be located on any of the other twenty-two matched Sn/Dn transistors, allowing for easier board layout. The translator?s transistors provides excellent ESD protection to lower voltage devices and at the same time protect less ESD resistant devices.
