Notes
1. “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply
that the devices should be operated at these limits. The table of “Electrical Characteristics” specifies conditions of device operation.
2. Current into device pins is defined as positive. Current out of device pins is defined as negative. All voltages are referenced to ground except:
V
OD1
and ΔV
OD1
.
3. All typicals are given for: V
CC
= +3.3V, T
A
= +25°C.
4. The PI90LV047A is a current mode device and only functions within datasheet specifications when a resistive load is applied to the driver
outputs typical range is (90 ohms to 110 ohms).
5. t
SKD1
|t
PHLD
– t
PLHD
| is the magnitude difference in differential propagation delay time between the positive going edge and the negative going
edge of the same channel.
6. t
SKD2
is the Differential Channel-to-Channel Skew of any event on the same device.
7. t
SKD3
, Differential Part to Part Skew, is defined as the difference between the minimum and maximum specified differential propagation
delays. This specification applies to devices at the same V
CC
and within 5°C of each other within the operating temperature range.
8. t
SKD4
, part to part skew, is the differential channel-to-channel skew of any event between devices. This specification applies
to devices over recommended operating temperature and voltage ranges, and across process distribution. t
SKD4
is defined as
|Max – Min| differential propagation delay.
9. Generator waveform for all tests unless otherwise specified: f = 1 MHz, Z
O
= 50 ohms, t
r
≤1 ns, and t
f
≤1ns.
10. ESD Ratings:
HBM (1.5 kohms, 100pF) ≥10kV
EIAJ (0 ohm, 200pF) ≥1200V
11. Output short circuit current (I
OS
) is specified as magnitude only, minus sign indicates direction only.
12. C
L
includes probe and jig capacitance.
13. All input voltages are for one channel unless otherwise specified. Other inputs are set to GND.
14. f
MAX
generator input conditions: t
r
= t
f
<1ns (0% to 100%), 50% duty cycle, 0V to 3V.
Output Criteria: duty cycle = 45%/55%, V
OD
>250mV, all channels switching.
