DESCRIPTION/ORDERING INFORMATION

The GTL2010 provides ten NMOS pass transistors (Sn and Dn) with a common gate (GREF) and a reference

transistor (SREF and DREF). 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 (SREF). When the Sn port is HIGH, the Dn port

is pulled to VCC by the pullup resistors.
