PC107A [Preliminary]

2137C–HIREL–03/04

Electrical

Characteristics

This section provides the AC and DC electrical specifications and thermal characteris-

tics for the PC107A.

Static Characteristics

DC Electrical Specification

Table 7 provides the DC electrical characteristics for the PC107A.

At recommended operating conditions (see Table 3 on page 12)

Notes:

1. These specifications are for the default driver strengths indicated in Table 8 on page 22.

2. See Figure 23 on page 35 for pins with internal pull-up resistors.

3. The minimum Input high voltage is not compliant with the PCI Local Bus Specification (Rev 2.1) which specifies 0.5*OV

DD for

minimum input high voltage.

4. Leakage current is measured on input pins and on output pins in the high impedance state. The leakage current is mea-

sured for nominal OV

DD/LVDD and VDD or both OvDD/LVDD and VDD must vary in the same direction.

5. See Table 8 on page 22 for the typical drive capability of a specific signal pin based upon the type of output driver associ-

ated with that pin as listed in Table 1 on page 5.

6. Capacitance is periodically sampled rather than 100% tested.
