VDD 1 6 VTT GND 2 5 GTL_REF S0 3 4 S1 DESCRIPTION/ORDERING INFORMATION
The SN74GTL3004 provides for a selectable GTL Voltage Reference (GTL VREF). The value of the GTL VREF can
be adjusted using S0 and S1 select pins.
The S0 and S1 pins contain glitch-suppression circuitry for excellent noise immunity. When left floating, the S0
and S1 control input pins have 100-kΩ pullups that set the GTL VREF default value to the 0.67 Г— VTT ratio …
