7.11Open Drain Test Circuit

Figure 11 is a test circuit that may be used on automated test equipment (ATE) to test for validity on open-drain pins.

Refer to Table 12, “General AC and DC Characteristics,” on page 32 for timing requirements.

VTermination1

50 Ω ±3%

Open-Drain Pin

IOL = Output Current2

Notes:

1.VTermination = 1.2 V for VID and FID pins VTermination = 1.0 V for APIC pins

2.IOL = –6 mA for VID and FID pins IOL = –9 mA for APIC pins
