JAJSF58O MARCH 2001 – April 2018 SN65HVD230 , SN65HVD231 , SN65HVD232
PRODUCTION DATA.
The unique difference between the SN65HVD230 and the SN65HVD231 is that both driver and receiver are switched off in the SN65HVD231 when a logic high is applied to RS (pin 8). The device remains in a very low power-sleep mode until the circuit is reactivated with a logic low applied to RS (pin 8). While in this sleep mode, the bus-pins are in a high-impedance state, while the D and R pins default to a logic high.
