The QSFCT374T is a high-speed CMOS TTL-
compatible 8-bit buffered registers with a buffered
common clock and a buffered output enable control.
The QSFCT2374T is a 25鈩?resistor output version
useful for driving transmission lines and reducing
system noise. Data is stored in the register on the
rising edge of the clock. The FCT374 is a non-
inverting device. The high output current I
OL
and I
OH
drive high capacitance loads. All inputs have clamp
diodes for undershoot noise suppression. All outputs
have ground bounce suppression (see QSI Applica-
tion Note AN-001), and outputs will not load an active
bus when V
CC
is removed from the device.
