Semiconductor AC characteristics measuring conditions 1. Input/output signal
VOH VIH TEST POINT VOL VIL VIL VOL VIH
MSM85C154HVS
VOH
*
The input signals in AC test mode are either VOH (logic "1") or VOL (logic "0") input signals where logic "1" corresponds to a CPU output signal waveform measuring point in excess of VIH, and logic "0" to a point below VIL.
2. Floating
VOH Floating VIH VIL VIH VIL VOH

*
The port 0 floating interval is measured from the time the port 0 pin voltage drops below VIH after sinking to GND at 2.4 mA when switching to floating status from a "1" output, and from the time the port 0 pin voltage exceeds VIL after connecting to a 400 mA source when switching to floating status from a "0" output.

Notes for Mounting the Surface Mount Type Package The SOP, QFP, TSOP, SOJ, QFJ (PLCC), SHP and BGA are surface mount type packages, which are very susceptible to heat in reflow mounting and humidity absorbed in storage. Therefore, before you perform reflow mounting, contact Oki's responsible sales person for the product name, package name, pin number, package code and desired mounting conditions (reflow method, temperature and times).
