Functional diagram I/O4 VCC I/O3 I/O1 GND I/O2 Applications Where transient overvoltage protection in ESD sensitive equipment is required, such as: ■ Computer ■ Portable healthcare equipment ■ Printers ■ Communication systems ■ Cellular phone handsets and accessories ■ Video equipment October 2012 This is information on a product in full production. Description The ESDALCL6-4P6A is an ESD protection array designed to protect data lines or other I/O ports against ESD transients. This device is ideal for applications where reduced line capacitance, board space saving and low leakage currents are required. Its low leakage current makes it suitable for portable equipment where battery consumption is a key factor and in analog front end where low leakage currents are mandatory for measurements precision.
