mu9c4485a Music Semiconductors, Inc., mu9c4485a Datasheet - Page 25

• Manufacturer Part Number: mu9c4485a
• Description: Wideport Lancam? Family
• Manufacturer: Music Semiconductors, Inc.

Notes:
1. -1.0V for a duration of 10 ns measured at the 50% amplitude points for Input-only lines (Figure 8).
2. Common I/O lines are clamped, so that signal transients cannot fall below -0.5V.
3. Over Ambient Operating Temperature and Vcc(min) to Vcc(max).
4. See Table 8.
5. Control signals are /W, /CM, and /EC.
6. With load specified in Figure 7, Test Load A.
7. With load specified in Figure 7, Test Load B.
8. /E must be HIGH during this period to ensure accurate default values in the configuration registers.
9. With output and I/O pins unloaded.
10. TEST1 and TEST2 may not be implemented on all versions of these products.
