Fairchild Semiconductor 

Test Circuits

FIGURE 1. AC Test Circuit

Notes:

VCC, VCCA = +2V, VEE = −2.5V

L1 and L2 = Equal length 50Ω impedance lines

RT = 50Ω terminator internal to scope

Decoupling 0.1 µF from GND to VCC and VEE

All unused outputs are loaded with 50Ω to GND

CL = Fixture and stray capacitance ≤ 3 pF
