Quad 18V Pin Electronics Driver/Window Comparator
ISL55100A
The ISL55100A is a Quad pin driver and window comparator
fabricated in a wide voltage CMOS process. It is designed
specifically for Test During Burn In (TDBI) applications, where
cost, functional density and power are all at a premium.
This IC incorporates four channels of programmable drivers
and window comparators into a small 72 Ld QFN package.
Each channel has independent driver levels, data and high
impedance control. Each receiver has dual comparators, which
provide high and low threshold levels.
The ISL55100A uses differential mode digital inputs and can
therefore mate directly with LVDS or CML outputs.
Single-ended logic families are handled by connecting one of
the digital input pins to an appropriate threshold voltage (e.g.,
1.4V for TTL compatibility). The comparator outputs are
single-ended and the output levels are user defined to mate
directly with any digital technology.
The 18V driver output and receiver input ranges allow this
device to interface directly with TTL, ECL, CMOS (3V, 5V and
7V), LVCMOS and custom level circuitry, as well as the high
voltage (super voltage) level required for many special test
modes for Flash Devices.
