FAST CMOS 16-BIT BIDIRECTIONAL TRANSCEIVERS
MILITARY AND COMMERCIAL TEMPERATURE RANGES
FEATURES: (Cont'd.)
• Features for FCT166245T/AT/CT:
– Light Drive A Port: ±8mA (commercial),
±6mA (military)
– High Drive B Port: +64mA, –32mA (commercial),
+48mA, –24mA (military)
– Minimal system switching noise
– Typical VOLP (Output Ground Bounce) < 0.25V at
VCC = 5V,TA = 25°C (A Port Switching)
• Features for FCT162H245T/AT/CT/ET:
– Bus Hold retains last active bus state during 3-state
– Eliminates the need for external pull up resistors
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.
