Notes to tables:
(1) Operating conditions: VCC = 5 V ± 5%, TA = 0° C to 70° C for commercial use.
CC = 5 V ± 5%, TA = –40° C to 85° C for industrial use.
V
(2) If the device enters standby mode and remains inactive for approximately 75 ns, increase the time by the amount
shown. For EP220-10A, EP220-12, and EP224-10A, EP224-12 devices only.
(3) Measured with all outputs switching.
(4) The tPZX and tPXZ parameters are measured at ± 0.5 V from steady-state voltage that is driven by the specified
output load. The tPXZ parameter is measured with CL = 5 pF and with all eight outputs switching.
