5 Description (continued)

Designed for operation in especially harsh environments, the SN65HVD1040-Q1 features cross-wire, overvoltage, and loss of ground protection from –27 V to 40 V, overtemperature protection, a –12-V to 12-V common-mode range, and withstands voltage transients from –200 V to 200 V, according to ISO 7637.

STB (pin 8) provides two different modes of operation: high-speed mode or low-current standby mode. The high-speed mode of operation is selected by connecting STB (pin 8) to ground.

If a high logic level is applied to the STB pin of the SN65HVD1040-Q1, the device enters a low-current standby mode, while the receiver remains active in a low-power bus-monitor standby mode.

In the low-current standby mode, a dominant bit greater than 5 µs on the bus is passed by the bus-monitor circuit to the receiver output. The local protocol controller may then reactivate the device when it needs to transmit to the bus.

A dominant time-out circuit in the SN65HVD1040-Q1 prevents the driver from blocking network communication with a hardware or software failure. The time-out circuit is triggered by a falling edge on TXD (pin 1). If no rising edge is seen before the time-out constant of the circuit expires, the driver is disabled. The circuit is then reset by the next rising edge on TXD.

SPLIT (pin 5) is available as a VCC/2 common-mode bus voltage bias for a split-termination network (see SPLIT).

The SN65HVD1040 is characterized for operation from –40°C to 125°C.
