2004 Sep 29

FEATURES

2.5 V, 3.3 V, and 5 V buses which allows direct interface with GTL,

GTL+, LVTTL/TTL and 5 V CMOS levels

(Sn/Dn)

200 V MM per JESD22-A115, and 1000 V per JESD22-C101

APPLICATIONS

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

bi-directional low voltage (e.g., 1.0 V, 1.2 V, 1.5 V, or 1.8 V)

signal levels or GTL/GTL+ translation to LVTTL/TTL signal levels.

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 GTL2002

provides 2 NMOS pass transistors (Sn and Dn) with a common gate

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

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,

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.
