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.
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.

Differential Mode:
Eight lines may be protected differentially
(line-to-line) by connecting Inputs/Outputs
at pins 1 - 16.
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.
