–
Light Drive A Port:
DESCRIPTION: (Cont'd.)
load (<100pF). The buffers are designed to limit the output
current to levels which will avoid noise and ringing on the
signal lines without using external series terminating resis-
tors. These parts have a
±
8mA driver on the "A" Port and a
+64/–32mA driver on the "B" Port, making them ideal for
interfacing noisy system busses to noise sensitive interfaces.
The FCT162H245T have "Bus Hold" which retains the
input's last state whenever the input goes to high impedance.
This prevents "floating" inputs and eliminates the need for
pull-up/down resistors.
