62 / 76 page ![]() ICS1531 Rev N 12/1/99 December, 1999 62 Chapter 9 AC/DC Operating Conditions ICS1531 Data Sheet - Preliminary Copyright © 1999, Integrated Circuit Systems, Inc. All rights reserved. 9.4 AC Operating Characteristics 9.5 DC Operating Characteristics This section lists the DC operating characteristics for the ICS1531. 9.5.1 DC Operating Characteristics for Supply Current. Note: All VDD measurements are taken with respect to VSS (which equals 0 V). 9.5.2 DC Operating Characteristics for Digital Inputs Table 9-6 lists DC operating characteristics for the following ICS1531 TTL input pins: • HSYNC • PDEN • SBADR • SCL • SDA (Input mode only. For output mode, see Table 9-7.) Note: All VDD measurements are taken with respect to the VSS pin (which equals 0 V). Note 1. Typically guaranteed by design. 9.5.3 DC Operating Characteristics for SDA Digital Pin, in Output Mode Table 9-7 lists DC characteristics for the SDA pin output mode. (For input mode, see Table 9-6.)
