PRODUCT
TTL monitor prove pod
(for LE-200PR/LE-150PR)

OP-5M

Overview

A connection probe for monitoring TTL-level communication lines. The input level supports serial communication of IC signal level at 2.5V, 3.3V, and 5V when monitoring. Furthermore, it is possible to eject voltage for external pull-up. It is the most suitable to evaluate serial communications etc. between LSI on the print board by directly connecting with the test clip.
