+5V, RS-232 Transceivers
with 0.1F External Capacitors
Shutdown and Enable Control
In shutdown mode, the MAX200/MAX205/MAX206/
MAX211/MAX213 charge pumps are turned off, V+ is
pulled down to VCC, V- is pulled to ground, and the
transmitter outputs are disabled. This reduces supply
current typically to 1A (15A for the MAX213). The time
required to exit shutdown is 1ms, as shown in Figure 5.
All receivers except R4 and R5 on the MAX213 are put
into a high-impedance state in shutdown mode. The
MAX213’s R4 and R5 receivers still function in shutdown
mode. These two receivers are useful for monitoring
external activity while maintaining minimal power con-
sumption.
The enable control is used to put the receiver outputs
into a high-impedance state, so that the receivers can be
connected directly to a three-state bus. It has no effect
on the RS-232 drivers or on the charge pumps.
MAX213 Receiver Operation in Shutdown
During normal operation, the MAX213’s receiver propa-
gation delay is typically 1Fs. When entering shutdown
with receivers active, R4 and R5 are not valid until 80Fs
after SHDN is driven low. In shutdown mode, propaga-
tion delays increase to 4Fs for a high-to-low or a low-to-
high transition.
When exiting shutdown, all receiver outputs are invalid
until the charge pumps reach nominal values (
< 2ms
when using 0.1FF capacitors).
