New Products 8A100-1 and 8A100-2 Dual High-Current
Photovoltaic Power Source
The 8A100-1 and 8A100-2 are dual high-current Photovoltaic Isolator (PVI) milli-watt power source.
These devices achieve the highest output current of any PVI on the market today
while providing a logic-level compatible output voltage.

MOS Capacitors reintroduced as of 9/1/2014
New versions of the C 616A and C 632A capacitors are being reintroduced this month.
They are slightly smaller than the earlier versions of the C
616 and C 632.
Die thickness is now 10mils and the capacitors are for epoxy die bond only.
It is otherwise identical to the earlier version of the C
616 and C 632.
** C 616A C 632A
New Product -- C 632A MOS Precision
The C632A SOIC chip-capacitor array is housed in an 8 pin SOIC
surface mount package that provides
user-adjustable capacitance values that range from as low as
1pF up to 63pF in 1pF increments.
This enables a multivalue MOS capacitor to be soldered directly to a pc board.
The final desired value is selected by making parallel
connections to the appropriate
1 pF, 2pF, 4pF, 8pF, 16pF
and 32pF leads.

DIG-1115-SM reintroduced as of 8/1/2014
A new version of the DIG-1115-SM is being reintroduced this month.
This is in response to requests for a lower LED Forward voltage on the DIG-2115-SM.
This new version will also have a changed Isc spec as compared to the previous version.
It is otherwise identical to the earlier version of the DIG-1115-SM.

About our patented active
dynamic discharge circuitry
ISO-gate microcircuits designated DIG-21-8-30-DD,
DIG-21-15-30-DD and DIG-22-8-30-DDx are
optically coupled floating power sources used primarily to
control power MOSFETS when electrical isolation between input
and output is required. The dynamic discharge circuitry
additionally causes rapid, active turn-off of the MOSFET when
power to the input LED is interrupted.
patented dynamic discharge feature (US Patent 4,931,656)
guarantees break before make in most solid state relay
switching applications. And, since the turn-off is active,
the DD series is particularly effective for application in
noisy environments such as motor controllers.
the development of the DD series, photovoltaic MOSFET drivers
(ISO-GATES) consisted simply of an LED light source optically
coupled to a photovoltaic diode array. Circuitry to discharge
the MOSFET gate capacitance was either a resistor sized to
compromise the turn-on/turn-off time or some elaborate
multi-component turn-off scheme.
All of the above devices are available in a
variety of packages including gull-wing or straight leg
plastic DIPs and ceramic military packaging.
