MAX19005
Quad, Ultra-Low-Power,
200Mbps ATE Drivers/Comparators
Detailed Description
The MAX19005 is a four-channel, ultra-low-power,
pin-electronics IC for automated test equipment that
includes, for each channel, a two-level pin driver, a
window comparator, a passive load, and a Kelvin instru-
ment connection (Figure 2). All functions feature a -1V to
+5.2V operating range and the drivers include a high-
impedance mode. The comparators feature program-
mable output voltages, allowing optimization for different
CMOS interface standards. The loads have selectable
output resistance for optimizing DUT_ current loading.
The Kelvin paths allow accurate connection of an instru-
ment with Q25mA source/sink capability. Additionally, the
IC offers a low-leakage mode that reduces DUT_ leakage
current to less than 20nA.
Each of the four channels feature single-ended CMOS-
compatible inputs (DATA_ and RCV_) for control of the
driver signal path (Figure 3). The IC mode operations
are programmed through a 3-wire, low-voltage CMOS-
compatible serial interface.
The driver input is a high-speed multiplexer that selects
one of two voltage inputs: DHV_ and DLV_. This switch-
ing is controlled by high-speed inputs DATA_ and RCV_.
DATA_ and RCV_ are single-ended inputs with threshold
levels (VBBI). Each channel’s threshold levels are inde-
pendently buffered to minimize crosstalk.
DUT_ can be toggled at high speed between the buffer
output and high-impedance mode, or it can be placed
into low-leakage mode (Figure 3, Table 1). High-speed
input RCV_ and mode-control bit LLEAK_ control these
modes. In high-impedance mode, the bias current at
DUT_ is less than 2FA over the -1V to +5.2V range, while
the node maintains its ability to track high-speed signals.
In low-leakage mode, the bias current at DUT_ is further
reduced to less than 20nA, and signal tracking slows.
The nominal driver output resistance is 49.5I.
Comparators
The IC provides two independent high-speed com-
parators for each channel. Each comparator has one
input connected internally to DUT_ and the other
input connected to either CHV_ or CLV_ (Figure 2).
Comparator outputs are a logical result of the input
conditions, as indicated in Table 2.
The comparator output voltages are easily interfaced to
a wide variety of logic standards. Use buffered inputs
COMPHI and COMPLO to set the high and low output
voltages. For correct operation, COMPHI should be
greater than or equal to COMPLO. The comparator
50I output impedance provides source termination
COMPLO)/2.
