Product Description  
resistance (R1 in parallel with R2) should match the  
impedance of the trace. Ground-bounce and crosstalk  
are virtually eliminated using a proprietary lead-frame  
which includes four direct ground connections to the die  
substrate, as well as four double-bonded connections to  
VCC, for a total of 8 commons. In addition, the resistors  
are trimmed to a tight absolute tolerance of 1% which  
provides tight impedance-matching and results in greatly  
reduced reflections. This unique proprietary design  
provides optimal signal integrity.  
High speed logic devices like HSTL (High Speed  
Transceiver Logic) demand unique, high speed bus  
terminations. The dual Thévenin termination network  
provides 16 terminating channels per package, and  
optimizes signal integrity by reducing reflections and  
ringing. The terminations are available in a range of  
standard values and are ideal for use in HSTL busses.  
As seen in the schematic, R1 is typically tied to VCC and  
serves as a pull-up resistor, while R2 functions as a pull-  
down resistor and is tied to ground (or the most negative  
supply voltage). In addition, the equivalent Thévenin
