FEATURES:
• CMOS power levels: <7.5mW static
• Undershoot clamp diodes on all inputs
• 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
• Std., A, and C speed grades with 4.1ns tPD for C
• IOL = 12mA
• Available in SOIC and QSOP packages
DESCRIPTION:
The IDTQS74FCT2244T is an 8-bit buffer/line driver with three-state
outputs and a 25Ω resistor, ideal for driving transmission lines and reducing
system noise. The 2244 series part can replace the 244 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.
