Product Description
The PACUSB-D1/D2/D3 is a single-channel USB
downstream-port termination network. It integrates
EMI/RFI filter components R1 and C1, as recom-
mended by the USB specification as well as the
required 15k
Ω
pull-down resistors (R2) to GND. In
addition, PACUSB-D1/D2/D3 provides a very high
level of protection for sensitive electronic components
that may be subjected to electrostatic discharge (ESD).
The device pins will safely dissipate ESD strikes of
+15kV, exceeding the maximum requirements of the
IEC 61000-4-2 international standard. Using the MIL-
STD-883D (Method 3015) specification for Human
Body Model (HBM) ESD, all pins are protected from
contact discharges to +20kV.
There are three options for the value of the series
resistor R1: 15
Ω
, 22
Ω
, and 33
Ω
. This series resis-
tance, plus the USB driver output resistance, must be
close to the USB cable’s characteristic impedance of
45
Ω
(each side) to minimize transmission line reflec-
tions.
The PACUSB-D1/D2/D3 is manufactured in a 5-pin
SC70 or a 5-pin SOT23 package and is available with
optional lead-free finishing.
