59 / 72 page ![]() 8.0 Device Characteristics (Continued) Revision 1.2 59 www.national.com 8.1.3 Capacitance 8.1.4 Power Consumption under Recommended Operating Conditions 8.1.5 Voltage Thresholds 8.2 DC CHARACTERISTICS OF PINS, BY I/O BUFFER TYPES The following tables summarize the DC characteristics of all device pins described in the Chapter 1.2 on page 9. The char- acteristics describe the general I/O buffer types defined in Table 1. For exceptions, refer to Section 8.2.8. The DC charac- teristics of the system interface meet the PCI2.2 3.3V DC signaling. 8.2.1 Input, PCI 3.3V Symbol: INPCI Symbol Parameter Min2 Typ1 1. TA = 25°C, f = 1 MHz Max2 2. Not tested.
