APPLICATION INFORMATION
features of the SN65HVD230Q, SN65HVD231Q, and SN65HVD232Q (continued)
The bus pins are also maintained in a high-impedance state during low V
CC
conditions to ensure glitch-free
power-up and power-down bus protection for hot-plugging applications. This high-impedance condition also
means that an unpowered node will not disturb the bus. Transceivers without this feature usually have a very
low output impedance. This results in a high current demand when the transceiver is unpowered, a condition
that could affect the entire bus.

R
S
(pin 8) of the SN65HVD230Q and SN65HVD231Q provides for three different modes of operation:
high-speed mode, slope-control mode, and low-power standby mode.
high-speed mode
The high-speed mode can be selected by applying a logic low to Rs (pin 8). The high-speed mode of operation
is commonly employed in industrial applications. High-speed allows the output to switch as fast as possible with
no internal limitation on the output rise and fall slopes. The only limitations of the high-speed operation are cable
length and radiated emission concerns, each of which is addressed by the slope control mode of operation.
If the low-power standby mode is to be employed in the circuit, direct connection to a DSP output pin can be
used to switch between a logic-low level (< 1 V) for high speed mode operation, and the logic-high level (> 0.75
V
CC
) for standby mode operation. Figure 29 shows a typical DSP connection, and Figure 30 shows the
SN65HVD230Q driver output signal in high-speed mode on the CAN bus.
