EL1056AC EL1056C EL1056AC EL1056C Monolithic High-Speed Pin Driver Features           Wide g 12V output levels 250 ps dispersion 3 ns delay times 1V ns slew rate adjustable Low overshoot and aberrations in 50X systems 3-state output Power-down mode reduces output leakage to nanoamperes Overcurrent sense flag available to protect internal output devices Buffered analog inputs Differential logic inputs are compatible with ECL TTL and CMOS General Description The EL1056 is designed to drive high-quality test signals into close or terminated loads It has a dispersion of 250 ps or less whether due to signal size or direction of edge It can output a very wide 24V output span encompassing all logic families as well as analog levels The EL1056 is fabricated in Elantec’s oxide isolated process which eliminates the possibility of latch-up and provides a very durable circuit The output can be turned off in two ways the OE pins allow the output to be put in a high-impedance state which makes the output look like a large resistance in parallel with 3 pF even for back-driven signals with as much as 2 5V ms slew rate The E pins put the output in an even higher impedance state guaranteed to 150 nA leakage in the EL1056A This allows accurate measurements on the bus without disconnecting the EL1056 with a relay The EL1056 incorporates an output current sense which can warn the system controller that excessive output current is flowing The trip point is set by two external resistors...
