Philips Semiconductors Product data 22-bit bi-directional low voltage translator GTL2000 APPLICATIONS Bi-directional translation For the bi-directional 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 pull-up resistor (typically 200 kΩ). A filter capacitor on DREF is recommended.
Philips Semiconductors Product data 22-bit bi-directional low voltage translator GTL2000 Uni-directional down translation For uni-directional clamping, higher voltage to lower voltage, the GREF input must be connected to DREFand both pins pulled to the higher side VCC through a pull-up resistor (typically 200 kΩ). A filter capacitor on DREF is recommended. Pull up resistors are required if the chipset I/O are open drain.
Philips Semiconductors Product data 22-bit bi-directional low voltage translator GTL2000 Sizing pull-up resistor The pull-up resistor value needs to limit the current through the pass transistor when it is in the “on” state to about 15 mA. This will guarantee a pass voltage of 260 to 350 mV. If the current through the pass transistor is higher than 15 mA, the pass voltage will also be higher in the “on” state.
