HIN213E Operation in Shutdown
The HIN213E features two receivers, R4 and R5, which
remain active in shutdown mode. During normal operation
the receivers propagation delay is typically 0.5
s. This
propagation delay may increase slightly during shutdown.
When entering shut down mode, receivers R4 and R5 are
not valid for 80
s after SD = VIL. When exiting shutdown
mode, all receiver outputs will be invalid until the charge
pump circuitry reaches normal operating voltage. This is
typically less than 2ms when using 0.1
F capacitors.
Application Information
The HIN2XXE may be used for all RS-232 data terminal and
communication links. It is particularly useful in applications
where
±12V power supplies are not available for
conventional RS-232 interface circuits. The applications
presented represent typical interface configurations.
A simple duplex RS-232 port with CTS/RTS handshaking is
illustrated in Figure 7. Fixed output signals such as DTR
(data terminal ready) and DSRS (data signaling rate select)
is generated by driving them through a 5k
resistor
connected to V+.
In applications requiring four RS-232 inputs and outputs
(Figure 8), note that each circuit requires two charge pump
capacitors (C1 and C2) but can share common reservoir
capacitors (C3 and C4). The benefit of sharing common
reservoir capacitors is the elimination of two capacitors and
the reduction of the charge pump source impedance which
effectively increases the output swing of the transmitters.
