Equivalent circuits model subtle traits of advanced CMOS ICs You can model the outputs of advanced CMOS logic (ACL) as linear LRC networks and gain valuable information about the ICs' ground-bounce and overshoot characteristics. Using these networks, you can also evaluate and improve the test fixtures for the devices. This article compares two quad AND-gate devices: a Fairchild 74AC08 (date code 8619), which has corner-pin connections for V.sub.CC and ground; and a Signetics 74AC1108 (date code 8639), which has center-pin V.sub.CC and ground connections.

The test setup used to produce the waveform displays for the examples in the text uses a HewLett-Packard Model ...
