74ACQ574 • 74ACTQ574
Quiet Series Octal D-Type Flip-Flop
with 3-STATE Outputs
General Description
Features
■ ICC and IOZ reduced by 50%
The ACQ/ACTQ574 is a high-speed, low-power octal D-
type flip-flop with a buffered Common Clock (CP) and a
buffered common Output Enable (OE). The information
presented to the D inputs is stored in the flip-flops on the
LOW-to-HIGH clock (CP) transition.
■ Guaranteed simultaneous switching noise level and
dynamic threshold performance
■ Guaranteed pin-to-pin skew AC performance
■ Inputs and outputs on opposite sides of the package
allowing easy interface with microprocessors
ACQ/ACTQ574 utilizes FACT Quiet Series technology to
guarantee quiet output switching and improve dynamic
threshold performance. FACT Quiet Series features GTO
output control and undershoot corrector in addition to a
split ground bus for superior performance.
■ Functionally identical to the ACQ/ACTQ374
■ 3-STATE outputs drive bus lines or buffer memory
address registers
The ACQ/ACTQ574 is functionally identical to the
ACTQ374 but with different pin-out.
■ Outputs source/sink 24 mA
■ Faster prop delays than the standard AC/ACT574

Functional Description
The ACQ/ACTQ574 consists of eight edge-triggered flip-
flops with individual D-type inputs and 3-STATE true out-
puts. The buffered clock and buffered Output Enable are
common to all flip-flops. The eight flip-flops will store the
state of their individual D-type inputs that meet the setup
and hold time requirements on the LOW-to-HIGH Clock
(CP) transition. With the Output Enable (OE) LOW, the
contents of the eight flip-flops are available at the outputs.
When OE is HIGH, the outputs go to the high impedance
state. Operation of the OE input does not affect the state of
the flip-flops.

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.
VOLP/VOLV and VOHP/VOHV:
•
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 50Ω coaxial cable plugged into a standard
SMB type connector on the test fixture. Do not use an
active FET probe.
Equipment:
Hewlett Packard Model 8180A Word Generator
PC-163A Test Fixture
•
•
Measure VOLP and VOLV on the quiet output during the
Tektronics Model 7854 Oscilloscope
Procedure:

500Ω.
Verify that the GND reference recorded on the oscillo-
scope has not drifted to ensure the accuracy and repeat-
ability of the measurements.
2. Deskew the HFS generator so that no two channels
have greater than 150 ps skew between them. This
requires that the oscilloscope be deskewed first. It is
important to deskew the HFS generator channels
before testing. This will ensure that the outputs switch
simultaneously.
V
ILD and VIHD:
•
Monitor one of the switching outputs using a 50Ω coaxial
cable plugged into a standard SMB type connector on
the test fixture. Do not use an active FET probe.
3. Terminate all inputs and outputs to ensure proper load-
ing of the outputs and that the input levels are at the
correct voltage.
•
•
•
First increase the input LOW voltage level, VIL, until the
output begins to oscillate or steps out a min of 2 ns.
Oscillation is defined as noise on the output LOW level
that exceeds VIL limits, or on output HIGH levels that

frequency of 1 MHz. Greater frequencies will increase
DUT heating and effect the results of the measure-
ment.
exceed VIH limits. The input LOW voltage level at which
oscillation occurs is defined as VILD
.
5. Set the HFS generator input levels at 0V LOW and 3V
HIGH for ACT devices and 0V LOW and 5V HIGH for
AC devices. Verify levels with an oscilloscope.
Next decrease the input HIGH voltage level, VIH, until
the output begins to oscillate or steps out a min of 2 ns.
Oscillation is defined as noise on the output LOW level
that exceeds VIL limits, or on output HIGH levels that
exceed VIH limits. The input HIGH voltage level at which
oscillation 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.
Note 19: VOHV and VOLP are measured with respect to ground reference.
Note 20: Input pulses have the following characteristics: f = 1 MHz,
tr = 3 ns, tf = 3 ns, skew < 150 ps.
