5 V tolerant inputs
Low stand-by current
Flow-through pinout for ease of printed circuit board trace routing
ESD protection exceeds 2000 V HBM per JESD22-A114, 200 V
MM per JESD22-A115, and 1000 V per JESD22-C101
Package offer: SSOP48, TSSOP48
Any application that requires bi-directional or unidirectional
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)

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 (G
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 (S
pulled to V
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,
S
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.
