The QSFCT373T is an 8-bit high-speed CMOS TTL-
compatible buffered latches with three-state outputs
that are ideal for driving high capacitance loads such
as memory and address buses. The 2373 is a 25鈩?/div>
resistor output version useful for driving transmission
lines and reducing system noise. The 2373 series
parts can replace 373 devices in existing designs to
reduce noise. All inputs have clamp diodes for under-
shoot noise suppression. All outputs have ground
bounce suppression (see QSI Application Note AN-
001), and outputs will not load an active bus when
V
CC
is removed from the device.
