STATIC ELECTRICAL CHARACTERISTICS

Table 4. Static Electrical Characteristics (continued)

Characteristics noted under conditions of 3.0 V ≤ VDD ≤ 5.5 V, 8.0 V ≤ VPWR ≤ 28V, -40°C ≤ TC ≤ 125°C unless otherwise

noted. Where applicable, typical values reflect the parameter’s approximate average value with VPWR = 13 V, TA = 25°C.

Notes

8. Thermal shutdown of 16 mA and 32 mA pull-up and pull-down current sources only. 4.0 mA and 2.0 mA current source/sink and all

other functions remain active.

9. This parameter is guaranteed by design; however it is not production tested.
