DC Electrical Characteristics

(GND = 0 V dc)

(VCC = 5.0 V dc ± 10%, TJ = -40° to +125°C, CL = 50 pF + 1 TTL Load)

The DC electrical characteristics of this device are shown in Table 10.

NOTES:

1. When EXTAL is AC coupled, VIHC - VILC Š 1 V must be true.

2. Input capacitance is periodically sampled and not 100% tested in production.
