(BUS HOLD)
DE S CRIPT ION:
The QS3389 provides a set of 20 active termnation circuits which pull data
bus signals to the voltage rails. This feature prevents bus signals fromfloating
in the threshold region of standard TTL I/O devices. The QS3389 can
replace resistor termnation solutions which add DC power dissipation and
increase component count. Input clamp diodes help to reduce reflections
and undershoot in transmssion line environments. Importantly, the term-
nator circuits pull signals to whichever logic state the signal previously held
(high or low). For this reason, this device is also referred to as a last value
latch. This device is appropriate for data bus applications where interfacing
devices have CMOS inputs with low input currents. These termnators
provide sufficient drive to overcome leakage currents and drive corre-
sponding signals away fromthe TTL threshold region.
The QS3389 is characterized for operation at 0°C to +70°C.
