Notes
1. Current into/out of any single lead
2. Surge input current duration is 3ms at 120Hz pulse repetition rate. Transient input current duration is
10s at 120Hz pulse repetition rate. Maximum input power, Pin, must be observed.
3. Maximum input power dissipation of 230mW allows an input IC junction temperature of 125°C at an
ambient temperature of Ta=70°C with a typical thermal resistance from junction to ambient of
jai=240°C/W. Excessive Pin and Tj may result in IC chip degradation.
4. Maximum output power dissipation of 210mW allows an output IC junction temperature of 125°C at an
ambient temperature of Ta=70°C with a typical thermal resistance from junction to ambient of
jao=265°C/W.
5. Maximum operating frequency is defined when output waveform (Pin 6) obtains only 90% of Vcc with
Rl=4.7kohm, Cl=30pF using a 5V square wave input signal.
6. The tPHL (tPLH) propagation delay is measured from the 2.5V level of the leading (trailing) edge of a
5.0V input pulse, 1s rise (fall) time, to the 1.5V level on the leading (trailing) edge of the output pulse.
7. Common mode transient immunity in Logic High (Low) Level is the maximum tolerable, positive
(negative), dVcm/dt on the leading (trailing) edge of the common mode pulse signal, Vcm, to ensure that the
output will remain in a Logic High (Low) state, ie. Vo>2.0V (Vo<0.8V).
8. In applications where dVcm/dt may exceed 50000V/s (such as static discharge), a series resistor Rcc
should be included to protect the detector IC from destructively high surge currents. The recommended
value for Rcc is 240ohm per volt of allowable drop in Vcc between Pin 8 and Vcc with a minimum value of
240ohm.
9. Logic low output level at Pin 6 occurs under the conditions of Vin>=Vth+ as well as the range Vin>Vth-
once Vin has exceeded Vth+. Logic high output level at Pin 6 occurs under the conditions of Vin<=Vth- as
well as the range of Vin<Vth+ once Vin has decreased below Vth-.
10. AC voltage is instantaneous voltage.
11. Device considered a two-terminal device: Pins 1,2,3,4 connected together, and Pins 5,6,7,8 connected
together.
