LOW POWER SHUTDOWN MODE
(ALL EXCEPT ADM3071E/ADM3074E/ADM3077E)
Low power shutdown mode is initiated by bringing both RE
high and DE low. In shutdown mode, the device draws less than
1 μA of supply current. RE and DE can be driven simulta-
neously, but the parts are guaranteed not to enter shutdown if
RE is high and DE is low for fewer than 50 ns. If the inputs are
in this state for 600 ns or more, the parts are guaranteed to enter
shutdown. Enable times t
ZH
and t
ZL
assume the part was not
originally in a low power shutdown state (see the Test Circuits
and Switching Characteristics section). Enable times t
ZH(SHDN)
and t
ZL(SHDN)
assume the part was originally shut down. It takes
drivers and receivers longer to become enabled from low power
shutdown mode (t
ZH(SHDN)
, t
ZL(SHDN)
) than from driver/receiver
disable mode (t
ZH
, t
ZL
).
DRIVER OUTPUT PROTECTION
The ADM307xE family features two methods to prevent
excessive output current and power dissipation caused by faults
Rev. A | Page 17 of 20
or by bus contention. Current limit protection on the output
stage provides immediate protection against short circuits over
the whole common-mode voltage range (see Figure 12 and
Figure 13). In addition, a thermal shutdown circuit forces the
driver outputs into a high impedance state if the die temper-
ature rises excessively.
TYPICAL APPLICATIONS
The ADM3072E/ADM3075E/ADM3078E transceivers are
designed for bidirectional data communications on multipoint
bus transmission lines. Figure 34 shows a typical network
applications circuit. The ADM3071E/ADM3074E/ADM3077E
transceivers are designed for point-to-point transmission lines
(see Figure 35). The ADM3070E/ADM3073E/ADM3076E
transceivers are designed for full-duplex RS-485 networks (see
Figure 36).
To minimize reflections, terminate the line at both ends
with a termination resistor (the value of the termination
resistor should be equal to the characteristic impedance of
the cable used) and keep stub lengths off the main line as
short as possible.
