Description
The RC7310 is a low cost High Speed Driver capable of over
250 MHz operation at ECL levels and greater than 1.2 V/ns
slew rate for 5 Vp-p output. The driver offers programmable
output levels between -3.0V and +8V and an output ampli-
tude up to 10 Vp-p. It is therefore capable of driving any
logic family such as ECL, TTL and CMOS. The high and
low limits of the output swing are set through the program
pins V
H
and V
L
, respectively. The transfer characteristic
from the program pins to the output pin is unity gain with
low offset (30 mV typical) and offset drift (0.1 mV/
cal). The V
H
and V
L
inputs have been buffered to operate
with low bias currents (1.0
m
A typical) allowing direct cou-
pling to the output of a DAC.

C typi-
The RC7310 is normally driven by ECL levels. However, the
input common mode range, -2V to +6V, is wide enough to
accommodate TTL or CMOS input signals. When driven
with a single ended signal the other input of the RC7310
must be tied to the appropriate threshold voltage.
The RC7310 is specified at nominal power supply values of
10V and -5.2V, and commensurate output voltage swing lim-
its of -3.0V and +8V.
