Description
The RC7311 Pin Electronics Driver is an economical alter-
native to standard pin electronics drivers in applications that
do not require three state capability in the driver. An example
of such an application would be the large number of input
address pins found in memory testers.
The driver output levels are programmable between -3.0V
and +8V to drive ECL, TTL and CMOS logic families. The
peak to peak output swing can vary from values lower than
300mV to values as high as 10V. With toggle rates greater
than 250MHz for ECL signals and typical slew rates of
2 V/ns for 5 Vp-p signal amplitudes, the RC7311 is compara-
ble with the requirements of state-of-the-art testers. The high
and low limits of the output swing are set through the pro-
gram pins V
H
and V
L
, respectively. The transfer characteris-
tic from the program pins to the output pin is unity gain with
low offset (30mV) and offset drift (0.1 mV/

C typical). The
The RC7311 is provided with high speed differential ECL
inputs for ease of interface with the differential ECL outputs
of a timing generator. The inputs have a wide voltage range,
-2V to +6V, so that if required, an input may be driven by
TTL or CMOS devices provided that the other input is tied to
the appropriate threshold value.
