HCPL-643X Datasheet, PDF (2/12 Pages) AVAGO TECHNOLOGIES LIMITED – Hermetically Sealed, Very High Speed, Logic Gate Optocouplers High radiation immunity

Each channel contains an AlGaAs light emitting diode
which is optically coupled to an integrated high gain
photon detector. This combination results in very high
data rate capability. The detector has a threshold with
hysteresis, which typically provides 0.25 mA of differen-
tial mode noise immunity and minimizes the potential for
output signal chatter. The detector in the single channel
units has a three state output stage which eliminates the
need for a pull-up resistor and allows for direct drive of a
data bus.
All units are compatible with TTL, STTL, LSTTL, and HCMOS
logic families. The 35 ns pulse width distortion speci-
fication guarantees a 10 MBd signaling rate at +125° C
with 35% pulse width distortion. Figures 13 through 16
show recommended circuits for reducing pulse width
distortion and optimizing the signal rate of the product.
Package styles for these parts are 8 pin DIP through hole
(case outlines P), and leadless ceramic chip carrier (case
outline 2). Devices may be purchased with a variety of
lead bend and plating options. See Selection Guide Table
for details. Standard Microcircuit Drawing (SMD) parts are
available for each package and lead style.
Because the same electrical die (emitters and detectors)
are used for each channel of each device listed in this
data sheet, absolute maximum ratings, recommended
operating conditions, electrical specifications, and per-
formance characteristics shown in the figures are similar
for all parts. Occasional exceptions exist due to package
variations and limitations and are as noted. Additionally,
the same package assembly processes and materials are
used in all devices. These similarities give justification for
the use of data obtained from one part to represent other
part’s performance for die related reliability and certain
limited radiation test results.
