Preliminary Data Sheet Monolithic, Low Capacitance TVS Array DESCRIPTION: TVA8LCXXX Series The TVA8LC series of monolithic transient voltage suppressors are designed for applications where voltage transients, caused by electrostatic discharge (ESD) and other induced voltage surges, can permanently damage sensitive components. These TVS diodes are characterized by extremely LOW CAPACITANCE while at the same time retaining their HIGH SURGE capability, extremely FAST RESPONSE time and LOW dynamic resistance. The 8LC series consists of 8 monolithic bi-directional TVS diode arrays and is specifically designed to protect multiple or single data lines with each channel being electrically independent for multiple I/O port protection. MECHANICAL CHARACTERISTICS: l l l l JEDEC MS-012AA small outline package (SOP) or 16 pin DIP Solder temperature: 265oC for 10 seconds Readily solderable terminals APPLICATIONS: l l l l l ESD & surge protection for power lines & I/O ports TTL and MOS Bus Lines RS-232, RS-422 and RS-485 data lines High speed logic High speed data & video transmission SCHEMATIC: This series will meet the surge requirements of IEC 1000-4-2 Level 4 (Formerly IEC 801-2), “Human Body Model” for air and contact discharge.

Common Mode: Bi-directional protection of eight lines is achieved by connecting Inputs/Outputs at pins 1 - 8. Pins 9 - 16 are connected to ground. Note: Device is symmetrical so connections may be reversed to serve a specific application. Typical Application (Data line protection) Line 1 thru 4 Time (µs) TVA8LCXXX Series TVS Array
