Quiet Series Octal Buffer/Line Driver
with TRl-STATE8 Outputs
General Description
The 'ACO/'ACT0244 is an octal buffer and line driver de-
signed to be employed as a memory address driver, clock
driver and bus oriented transmitter or receiver which pro-
vides improved PC board density. The ACQ/ACTQ utilizes
NSC Quiet Series technology to guarantee quiet output
switching and improved dynamic threshold performance.
FACT Quiet SeriesTM features GTOTM output control and
undershoot Corrector in addition to a split ground bus for
superior performance.

FACT Noise Characteristics
The setup of a noise characteristics measurement is critical
to the accuracy and repeatability of the tests. The following
is a brief description of the setup used to measure the noise
characteristics of FACT.
Equipment:
Hewlett Packard Model 8180A Word Generator
PC-163A Test Fixture
Tektronics Model 7854 Oscilloscope
Procedure:
1. Verify Test Fixture Loading: Standard Load 50 pF, 500n.
2. Deskew the word generator so that no two channels have
greater than 150 ps skew between them. This requires
that the oscilloscope be deskewed first. Swap out the
channels that have more than 150 ps of skew until all
channels being used are within 150 ps. It is important to
deskew the word generator channels before testing. This
will ensure that the outputs switch simultaneously.
3. Terminate all inputs and outputs to ensure proper loading
of the outputs and that the input levels are at the correct
voltage.
4. Set Vcc to 5.0V.
5. Set the word generator to toggle all but one output at a
frequency of 1 MHz. Greater frequencies will increase
DUT heating and affect the results of the measurement.
6. Set the word generator input levels at 0V LOW and 3V
HIGH for ACT devices and 0V LOW and 5V HIGH for AC
devices. Verify levels with a digital volt meter.
VOLP/VOLV and VOHP/VOHV=
0 Determine the quiet output pin that demonstrates the
greatest noise levels. The worst case pin will usually be
the furthest from the ground pin. Monitor the output volt-
ages using a 500 coaxial cable plugged into a standard
SMB type connector on the test fixture. Do not use an
active FET probe.
q Measure VOLP and vow on the quiet output during the
HL transition. Measure VOHp and VOHV on the quiet out-
put during the LH transition.
- Verify that the GND reference recorded on the oscillo-
scope has not drifted to ensure the accuracy and repeat-
ability of the measurements.
VILD and VIHD:
q Monitor one of the switching outputs using a 500 coaxial
cable plugged into a standard SMB type connector on
the test fixture. Do not use an active FET probe.
. First increase the input LOW voltage level. VIL, until the
output begins to oscillate. Oscillation is defined as noise
on the output LOW level that exceeds VIL limits, or on
output HIGH levels that exceed Vm limits. The input
LOW voltage level at which oscillation occurs is defined
as VILD~
. Next increase the input HIGH voltage level on the word
generator, VH4 until the output begins to oscillate. Oscilla-
tion is defined as noise on the output LOW level that
exceeds " limits, or on output HIGH levels that exceed
VIH limits. The input HIGH voltage level at which oscilla-
tion occurs is defined as VIHD.
. Verify that the GND reference recorded on the oscillo-
scope has not drifted to ensure the accuracy and repeat-
ability of the measurements.
