DESCRIPTION/ORDERING INFORMATION
The GTL2010 provides ten NMOS pass transistors (Sn and Dn) with a common gate (G_REF) and a reference
transistor (S_REF and D_REF). The low ON-state resistance of the switch allows connections to be made with
minimal propagation delay. With no direction control pin required, the device allows bidirectional voltage
translations any voltage (1 V to 5 V) to any voltage (1 V to 5 V).
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_REF). When the Sn port is HIGH, the Dn port
is pulled to V_CC by the pullup resistors.
