Description
Features
The E7802 is a dual-channel pin electronics driver and
window comparator product fabricated in a wide voltage
Bi-CMOS process. It is designed specifically for Test During
Burn In (TDBI) applications and low cost testers, where cost,
functional density, and power are all at a premium.
The E7802 incorporates two channels of programmable
drivers and window comparators into a small 5 mm X 5
mm QFN package. Each channel has per pin driver levels,
data, and high impedance control, along with per-pin high
and low window comparator threshold levels.
The E7802 was specifically designed to offer a low cost,
high density driver and window comparator solution with
excellent small swing performance and stable timing
characteristics.
• 15V I/O Range
• 200 mA DC Current Capability
• Low Output Impedance
• 50 MHz Operation
• Driver Short Circuit Protection
• Per-Pin Flexibility
• Programmable Input Thresholds
• LVTTL Compatible I/O
• Small footprint (5 mm x 5 mm QFN with Exposed
Heat Slug)
• Improved Small Signal Swing and Timing
Performance
• Low Preshoot/Overshoot/Undershoot
• Pin Compatible with E7801 and E7803
A 15V driver output and receiver input range allow the
E7802 to interface directly with TTL, ECL, CMOS (3V, 5V,
and 7V), LVCMOS, and custom level circuitry, as well as high
voltage levels required for many special test modes in Flash
Devices and for stressing devices under test.
