OPERATION Designed for the unique requirements of battery-backed systems, the DS276 provides a low-power full-or half-duplex interface to an RS-232 serial port. Typically, a designer must use an RS-232 device which uses system power during both negative and positive transitions ...

As a prime example, the DS276 will not meet the RS-232 requirement that the signal levels be at least 5 volts minimum when terminated =load and V will be present at TX when spacing under ...

NOTES: 1. This circuit as shown does not meet the RS-232 requirement for signal levels (high-level output voltage). However, as most RS-232 receivers will interpret any voltage over space this will normally consequence. Alternatively, ...
