Description
Edge647
Pin Electronics Driver, Window
Comparator, and Switch Matrix
Applications
The Edge647 is an integrated trinary driver, window • Low Cost Automatic Test Equipment
comparator, and switch matrix pin electronics solution
manufactured in a wide voltage CMOS process. It is
designed for automatic test equipment and
instrumentation where cost, functional density, and power
are all at a premium.
The tristatable driver is capable of generating 3 levels -
one for a logic high, one for a logic low, and one for either
a termination voltage or a special programming voltage.
The on-board window comparator effectively determines
whether the DUT is in a high, low, or intermediate state. Functional Block Diagram
The switches are included to allow such functions as PMU,
pull up, and pull down connections.
VH VTT VL
The Edge647 is intended to offer an extremely low leakage,
low cost, low power, small footprint, per pin solution for
100 MHz and below pin electronics applications. It is a
higher performance, pin and functionally compatible
version of the Edge646.

Circuit Description (continued)
Receiver Functionality
Load
The Edge647 supports an on-board window comparator.
CVB and CVA are high impedance analog inputs which
establish the threshold voltages. COMPA and COMPB are
the digital outputs which reflect the real time status of
VINP. Table 2 summarizes the relationship between the
threshold levels, VINP, and the output signals.

COMPA
COMPB
The Edge647 provides a total of 3 analog switches.
Individual switches vary in both their on resistance and
their on/off time (see Table 4).
Like the driver digital inputs, the switch matrix control inputs
SW0-3 EN* are technology independent as VBB
determines their threshold level. The switch control is
documented in Table 3.

Table 2. Comparator Truth Table
Comparator Outputs
The comparator outputs are 50 output impedance non-
tristatable drivers designed to cleanly drive 50
transmission lines without requiring any external series
termination resistors. Input pins LOW LEVEL and HIGH
LEVEL establish the logic 0 and 1 levels respectively. In
normal operation, LOW LEVEL would be connected to
ground and HIGH LEVEL would be connected to a system
VDD supply, producing CMOS digital swings at the output.

However, the comparator outputs are technology
independent in that they can drive PECL, 3V CMOS, ECL,
LV CMOS, GTL, and custom levels by varying LOW LEVEL
and HIGH LEVEL. For example, should a 3V swing be
desired, HIGH LEVEL could be connected to a 3.0V power
supply.
Table 4. Switch Matrix Characteristics
Do NOT leave any digital input pins floating.
Notice that HIGH LEVEL and LOW LEVEL provide both the
voltage level and the current for the comparator outputs.
HIGH LEVEL and LOW LEVEL may be varied between +5V
and -2V.
