Description
Edge4717D
Quad Channel, Per Pin
Precision Measurement Unit
Features
The Edge4717D is a precision measurement unit designed
for automated test equipment and instrumentation.
Manufactured in a wide voltage CMOS process, it is a
monolithic solution for a quad channel per pin PMU.
Each channel of the Edge4717D features a PMU that
can force or measure voltage over a typical 15V I/O range,
and supports 4 current ranges: ± 3.2 µA, ± 80 µA,
± 2 mA, ± 30 mA.
The Edge4717D has an on-board window comparator per
channel that provides two bits of information — DUT too
high and DUT too low. There is also a monitor pin which
provides a real time analog signal proportional to either
the voltage or current measured at the DUT.

Functional Block Diagram
The Edge4717D is designed to be a low power, low cost,
small footprint solution to allow high pin count testers to
support a PMU per pin.
On-board voltage clamps, with over-current detection,
provide protection to the DUT and 4717D.
The Edge4717D also has a sample-and-hold feature
available for capturing DUT current or voltage
measurements.
The Edge4717D is a design improvement to the Edge4717
that features:
– Increased FV/MV range
– Improved over-current detection circuit
functionality
– LVTTL comparator outputs (pull-up resistors
no longer required)
– Improved HiZ switching characteristics
– Improved Force Voltage Linearity
Applications
• Automated Test Equipment
- Memory Testers
- VLSI Testers
- Mixed Signal Tester
