This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
DESCRIPTION/ORDERING INFORMATION (CONTINUED)
R
S
(pin 8) provides for three modes of operation: high-speed, slope control, or low-power standby mode. The
high-speed mode of operation is selected by connecting R
S
directly to ground, allowing the driver output
transistors to switch on and off as fast as possible with no limitation on the rise and fall slope. The rise and fall
slope can be adjusted by connecting a resistor to ground at R
S
, since the slope is proportional to the pin's output
current. Slope control is implemented with a resistor value of 10 kΩ to achieve a slew rate of ≉ 15 V/μs, and a
value of 100 kΩ to achieve ≉ 2.0 V/μs slew rate. For more information about slope control, refer to the application
information section.
The SN65HVD233 enters a low-current standby mode, during which the driver is switched off and the receiver
remains active if a high logic level is applied to R
S
. The local protocol controller reverses this low-current standby
mode when it needs to transmit to the bus.
A logic high on the loopback (LBK, pin 5) of the SN65HVD233 places the bus output and bus input in a high-
impedance state. The remaining circuit remains active and available for the driver to receiver loopback, self-
diagnostic node functions without disturbing the bus.
