The F81439 is programmable, monolithic multi-protocol transceiver device that contains RS-232 and RS-485 / RS-422 drivers and receivers. The F81439 can be reconfigured into eight operating modes including one pure RS-232 (3TX/5RX), one RS-485 (1TX/1RX) driver (TX) half duplex mode, one RS-485 (1TX/1RX) receiver (RX) half duplex mode, RS-422 (1TX/1RX) full duplex mode, RS-485 (1TX/1RX) driver (TX) half duplex mode with built-in termination resistor, RS-422 (1TX/1RX) full duplex mode with built-in termination resistor, coexist RS-232 (TX/RX only) with RS-485 mode without the need for the bus switch IC and a shutdown mode which can be selected whenever you need by changing the logic state of the 3 mode selection pins.
The extra charge pumps deliver true RS-232 driver output voltage from a single power supply at either 3.3V ~ 5V. The F81439 requires only four 0.1uF capacitors for the charge pump. This item converts the 5 V input power to the ±10 V (norminal) required for RS-232 output levels. The F81439 meets the EIA-232-E V0.28 specification while using a single digital 3.3V or 5 V supply and particularly suites for those applications where ±12V is not available. A slew rate control pin configures driver outputs for either high data rate or slew-controlled data rates. Slew-controlled outputs minimize the problems that caused by the reflections and ringing on long or un-terminated cables.
The RS-422/RS-485 receiver and transceiver feature high impedance which allow up to 256 transceivers on a shared bus. When configured in RS-485/RS-422 mode, the driver may be individually enabled into tri-state, simplifying use on shared buses or bidirectional communication. All receivers have advanced failsafe protection to prevent oscillation when inputs are un- connected by defaulting to logic high output level. No external biasing resistors are required. In RS-232 mode each receiver input has a 5KΩ pull-down to ground. Differential Receivers will default to output logic 1 if inputs are floating, shorted or open but terminated.

What are the best tools for storing and using bitcoin today?Even if you don’t want to store any of your bitcoin on an exchange long-term, you’ll are mining it yourself). And even if you trust an exchange to store your bitcoin . , you’ll probably still want to keep some Bitcoin in a reliable bitcoin software wallet for making bitcoin purchases. Exchanges often take a couple of hours to batch and broadcast outgoing payments.

expound the actual teachings of the great explorer of the truth, the master-builder of human happiness. No one rejects, dislikes, or avoids pleasure itself, because it is pleasure, but because those who do not know how to pursue pleasure rationally encounter consequences that are extremely painful. Nor again is there anyone who loves or pursues or desires to obtain pain of itself, because it is pain, but in which toil and pain can procure him.

A wonderful serenity has taken possession of my entire soul, like these sweet mornings of spring which I enjoy with my whole heart. I am alone, and feel the charm of existence in this spot, which was created for the bliss of souls like mine. I am so happy.

my dear friend, so absorbed in the exquisite sense of mere tranquil existence, that I neglect my talents.

I feel that I never was a greater artist than now. When, while the lovely valley teems with vapour around me, and the meridian sun strikes the upper surface of the impenetrable foliage of my trees, and but a few stray gleams steal into the inner sanctuary.
