Description
The E7804 is a quad channel, monolithic ATE pin electronics solution manufactured in a high-performance BiCMOS process.
The E7804 operates up to 33 MHz with up to 3V signals, and 00 MHz with 5V signals.
Each channel has a three-statable driver capable of generating 5.4V swings over a –0.2V, +5.2V range. Drivers have independent high and low input levels that are buffered internally. Drivers feature a self-calibrating source impedance, programmable in the range 48Ω to 110Ω. The source impedance of all drivers matches REREF/00, where REREF is the external reference resistor. Each channel’s dual comparator has a range of –2.0V to +5.5V.
