The GTL2000 2.5 V, 3.3 V, and 5 V busses which allows direct interface with provides 22 NMOS pass transistors (Sn and Dn) with a common GTL, GTL+, LVTTL/TTL and 5 V CMOS levels gate (G ) and a reference transistor (S and D ). The device REF REF REF allows bi-directional voltage translations between 1.0 V and 5.0 V Provides bi-directional voltage translation with no direction pin without use of a direction pin. Low 6.5 RDS resistance between input and output pins ON When the Sn or Dn port is low the clamp is in the ON-state and a (Sn/Dn) low resistance connection exists between the Sn and Dn ports. Assuming the higher voltage is on the Dn port, when the Dn port is Supports hot insertion high, the voltage on the Sn port is limited to the voltage set by the No power supply required - Will not latch up ). When the Sn port is high, the Dn port is reference transistor (S REF pulled to V by the pull up resistors. This functionality allows a CC 5 V tolerant inputs seamless translation between higher and lower voltages selected by Low stand-by current the user, without the need for directional control. Flow-through pinout for ease of printed circuit board trace routing All transistors have the same electrical characteristics and there is minimal deviation from one output to another in voltage or ESD protection exceeds 2000 V HBM per JESD22-A114, 200 V propagation delay. This is a benefit over discrete transistor voltage MM per JESD22-A115, and 1000 V per JESD22-C101 translation solutions, since the fabrication of the transistors is symmetrical. Because all transistors in the device are identical, Package offer: SSOP48, TSSOP48 S and D can be located on any of the other twenty-two REF REF matched Sn/Dn transistors, allowing for easier board layout. The APPLICATIONS translators transistors provides excellent ESD protection to lower voltage devices and at the same time protect less ESD resistant Any application that requires bi-directional or unidirectional devices. voltage level translation from any voltage between 1.0 V & 5.0 V to any voltage between 1.0 V & 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) 2 2 processor I C port translation to the normal 3.3 V and/or 5.0 V I C bus signal levels or GTL/GTL+ translation to LVTTL/TTL signal levels.
