RC Networks

Resistor-capacitor networks (RC networks) are integrated circuits (ICs) that combine resistor-capacitor circuit elements in a single chip. They are commonly used for filtering purposes, serving as EMI filters, ESD protection, bus terminations, and suppressor/snubber circuits. RC networks find applications in automotive noise suppression, I/O port protection, RFI suppression, power supply filtering, and memory interface termination.

These networks can include clamping diodes for voltage spike protection, Schottky barrier diodes for high-speed bus terminations, and resistor-capacitor combinations designed for noise suppression. They are also used for relay contact protection in high-voltage applications.

RC networks consist of arrays of resistor-capacitor circuit elements in series and parallel configurations, often in "PI" or "T" network arrangements for low pass filtering. Multiple channel devices are used for bus termination, typically incorporating a series resistor and capacitor with a shared ground pin for efficiency.

The specifications of RC networks include cut-off frequency, attenuation in the stop band, DC series resistance, and maximum current handling. They may also have exposed pads for improved heat dissipation.

These networks are employed to suppress transmission-line effects, enhance system performance, and reduce costs of passive components. They also play a role in EMI and RFI suppression at I/O ports of PCs, peripherals, workstations, LANs, WANs, and ATM networks.
