MULTIPLE SWITCH DETECTION INTERFACE WITH SUPPRESSED WAKE-UP

Motorola => Freescale 

Freescale Semiconductor, Inc.

STATIC ELECTRICAL CHARACTERISTICS (continued)

Characteristics noted under conditions of 3.1 V ≤ VDD ≤ 5.25 V, 8.0 V ≤ VPWR ≤ 16 V, -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.
