Applications Information

Functional Description

The EL1056 is a fully integrated pin driver for automatic test

systems. Pin drivers are essentially pulse generators whose

high and low levels can be externally programmed and

accurately switched in time, as well as incorporating an

output switch to disconnect the driver from a measurement

bus. Additionally, the EL1056 has programmable slewrate.

Control Voltage Inputs

The analog level inputs are named VINH and VINL, and the

output replicates them as controlled by logic inputs. The

analog inputs are buffered and have bandwidths of 35MHz

and slewrates of 25V/µs. For full slewrate, 4V of headroom

should be given to the inputs, that is VINH should be 4V less

than V+ or B+, and VINL should be 4V more positive than V-

or B-. At lower slewrates (ISR = 500µA or less), 3V of

headroom will suffice. Insufficient headroom causes

distorted output waveforms or delay errors in output

transitions. VINH may be lower in voltage than VINL, but the

output will not follow the control logic correctly. Furthermore,

VINH should be 200mV more positive than VINL (the

minimum output amplitude) for accurate switching.
