EL1056AC Datasheet Monolithic High-speed Pin Driver

Manufacturer: Elantec

Overview: EL1056AC EL1056C EL1056AC EL1056C Monolithic High-Speed Pin Driver.

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 Applications     Memory testers ASIC testers Functional board testers Analog digital incoming component verifiers  Logic emulators Connection Diagram 24-Lead Thermal SOL Package Ordering Information Part No EL1056CM Temp Range 0 C to a 75 C Package Outline 24-Lead MDP0027 Thermal SOL 24-Lead MDP0027 Thermal SOL EL1056ACM 0 C to a 75 C March 1993 Rev A and Heat-spreader 1056 – 1 Top View Note All information contained in this data sheet has been carefully checked and is believed to
