High speed operation
Although the EIA RS232 specification is for a relatively slow communications protocol, many applications require RS232 transceivers to operate at higher frequencies. Devices such as the LT1080, LT1081, and the LT1130 series share a common design for the drivers and receivers and are capable of operating over 100kBd.
Although the slew rate is controlled for all of the Linear Technology series of RS232 communications devices, for output levels limited to ±6V the transition time is fast enough to allow ...
