Electrical Characteristics
I/O Standard Specifications
Table 1–14 through Table 1–19 list input voltage (V_IH and V_IL), output voltage (V_OH and
V_OL), and current drive characteristics (I_OH and I_OL) for various I/O standards
supported by HardCopy IV devices. These tables also show the HardCopy IV device
family I/O standard specifications. Refer to the “Glossary” on page 1–32 for an
explanation of terms used in Table 1–14 through Table 1–19. V_OL and V_OH values are
valid at the corresponding I_OH and I_OL, respectively.
