IDTQS74FCT2823AT/BT
DESCRIPTION:
CMOS power levels: <7.5mW static
Undershoot clamp diodes on all outputs
True TTL input and output compatibility
Ground bounce controlled outputs
Reduced output swing of 0 to 3.5V
Ω
Built-in 25Ω series resistor outputs reduce reflection and other
system noise
• A and B speed grades
• I
OL
= 12mA
• Available in QSOP package
The IDTQS74FCT2823T is a 9-bit high-speed CMOS TTL-compatible
buffered register with 3-state outputs, with a 25Ω resister that is useful for
driving transmission lines and reducing system noise. The 2823 series parts
can replace the 823 series to reduce noise in an existing design. All inputs
have clamp diodes for undershoot noise suppression. All outputs have
ground bounce suppression. Outputs will not load an active bus when Vcc
is removed from the device.

NOTE:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause
permanent damage to the device. This is a stress rating only and functional operation
of the device at these or any other conditions above those indicated in the operational
sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect reliability.

Description
D Flip-Flop Data Inputs
When the clear input is LOW and
OE
is LOW, the Yx
outputs are LOW. When clear input is HIGH, data can
be entered into the register.
Clock Pulse for the register. Enters data into the register
on the LOW-to-HIGH transition.
Register 3-State Outputs
Clock Enable. When the clock enable is LOW, data
on the D
x
input is transferred to the Yx output on the
LOW-to-HIGH clock transition. When the clock
enable is HIGH, the Yx outputs do not change state,
regardless of the data or clock input transitions.
Output Control. When the
OE
input is HIGH, the Yx
outputs are in the high impedance state. When the
OE
input is LOW, the TRUE register data is present at the
Yx outputs.
