FEATURES:
• 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
• Built-in 25Ω series resistor outputs reduce reflection and other
system noise
• A, B, and C speed grades
• IOL = 12mA
• Available in SOIC and QSOP packages
DESCRIPTION:
The IDTQS74FCT2821T is a 10-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 2821 series parts
can replace the 821 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.
