LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC134).

; DOUT is open-circuit; clock signal at input CLK; f

DD
; data signal at input DIN: random pattern at 20 kHz to simulate 2400 bits/s data with noise; t
r
= t
f
= 5 ns.
The operating current will be higher than specified when the input signal amplitude is less than 100%
(equals V
SS
to V
DD
) or when longer rise/fall times are used. This is caused by the Schmitt-trigger circuits drawing
extra current.
