Levels

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

by the pullup resistors.

GTL2010 10-BIT BIDIRECTIONAL LOW-VOLTAGE TRANSLATOR www.ti.com SCDS221 – SEPTEMBER 2006 DESCRIPTION/ORDERING INFORMATION (CONTINUED) All transistors in the GTL2010 have the same electrical characteristics, and there is minimal deviation from one output to another in voltage or propagation delay. This offers superior matching over discrete transistor voltage-translation solutions where the fabrication of the transistors is not symmetrical.

GTL2010 10-BIT BIDIRECTIONAL LOW-VOLTAGE TRANSLATOR www.ti.com SCDS221 – SEPTEMBER 2006 APPLICATION INFORMATION Bidirectional Translation For the bidirectional clamping configuration (higher voltage to lower voltage or lower voltage to higher voltage), the GREF input must be connected to DREF and both pins pulled to HIGH-side VCC through a pullup resistor (typically 200 kΩ). A filter capacitor on DREF is recommended.

GTL2010 10-BIT BIDIRECTIONAL LOW-VOLTAGE TRANSLATOR www.ti.com SCDS221 – SEPTEMBER 2006 APPLICATION INFORMATION (continued) Unidirectional Down Translation For unidirectional clamping (higher voltage to lower voltage), the GREF input must be connected to DREF and both pins pulled to the higher-side VCC through a pullup resistor (typically 200 kΩ). A filter capacitor on DREF is recommended. Pullup resistors are required if the chipset I/Os are open drain.
PAGE 11
GTL2010 10-BIT BIDIRECTIONAL LOW-VOLTAGE TRANSLATOR www.ti.com SCDS221 – SEPTEMBER 2006 APPLICATION INFORMATION (continued) Unidirectional Up Translation For unidirectional up translation (lower voltage to higher voltage), the reference transistor is connected the same as for a down translation. A pullup resistor is required on the higher voltage side (Dn or Sn) to get the full HIGH level, since the GTL device only passes the reference source (SREF) voltage as a HIGH when doing an up translation.
PAGE 12
GTL2010 10-BIT BIDIRECTIONAL LOW-VOLTAGE TRANSLATOR www.ti.com SCDS221 – SEPTEMBER 2006 APPLICATION INFORMATION (continued) Sizing Pullup Resistor The pullup resistor value should limit the current through the pass transistor when it is in the on state to about 15 mA. This ensures a pass voltage of 260 mV to 350 mV. If the current through the pass transistor is higher than 15 mA, the pass voltage also is higher in the on state.
