Quiet Series™ Octal Latch with 3-STATE Outputs
Features
General Description
■ I and I reduced by 50%
The ACQ/ACTQ573 is a high-speed octal latch with buff-
ered common Latch Enable (LE) and buffered common
Output Enable (OE) inputs. The ACQ/ACTQ573 is func-
tionally identical to the ACQ/ACTQ373 but with inputs
and outputs on opposite sides of the package. The ACQ/
ACTQ utilizes Fairchild's Quiet Series™ technology to
guarantee quiet output switching and improved dynamic
threshold performance. FACT Quiet Series™ features
GTO™ output control and undershoot corrector in addi-
tion to a split ground bus for superior performance.

OZ
■ Guaranteed simultaneous switching noise level and
dynamic threshold performance
■ Guaranteed pin-to-pin skew AC performance
■ Improved latch-up immunity
■ Inputs and outputs on opposite sides of package allow
easy interface with microprocessors
■ Outputs source/sink 24mA

Functional Description
The ACQ/ACTQ573 contains eight D-type latches with
3-STATE output buffers. When the Latch Enable (LE)
input is HIGH, data on the D inputs enters the latches.
n
In this condition the latches are transparent, i.e., a latch
output will change state each time its D-type input
changes. When LE is LOW the latches store the informa-
tion that was present on the D-type inputs at setup time
preceding the HIGH-to-LOW transition of LE. The
3-STATE buffers are controlled by the Output Enable
(OE) input. When OE is LOW, the buffers are enabled.
When OE is HIGH the buffers are in the high impedance
mode but this does not interfere with entering new data
into the latches.

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.

be the furthest from the ground pin. Monitor the output

standard SMB type connector on the test fixture. Do

2. Deskew the HFS generator so that no two channels
