Description
The RC7316 Pin Electronics Driver is designed for use in
ultra high speed ATE systems which require pin drivers with
three state capability and high slew rates. The RC7316 has
the ability to drive a 50
W
transmission line of up to 2 feet in
length with a slew rate of 3.2 V/ns and repetition rate of over
550 MHz for ECL output levels. These features, combined
with a maximum output swing of 9.5 Vp-p over the range of
-3.0V to +7V, provide this circuit with the ability to test TTL,
CMOS, ECL and GaAs devices. The high and low limits of
the output swing are set through the program pins V
V
L
, respectively. The transfer characteristic from the pro-
gram pins to the output pin is unity gain with very low offset
drift. The V
H
and V
L
inputs have been buffered to operate
with low bias currents (1
m
A typical) allowing direct
coupling to the output of a DAC.
H
and
When the RC7316 is used on an I/O pin, it may be forced
into the high impedance state through the INH+ and INH-
differential inputs. In the high impedance state, excellent
isolation is provided between the output of the disabled
driver and the pin by virtue of low driver output capacitance
(3.0 pF typical) and low output leakage (10 nA typical).
The RC7316 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 voltage range of -2V
to +6V, so that if required, an input may be driven by TTL or
CMOS devices provided that the other input is fed to the
appropriate threshold value.
