TI's new SN75LBC786 combines four RS-423-B drivers/receivers with loopback circuits to provide fast data transmission, with hands-off testing of the drivers/receivers and partial testing of the lines.
Driver slew rates are controlled with only one resistor. The receivers are RS-232 compatible with the addition of external resistors to meet the RE-232 input resistance specification of 3 kilo-ohms to 7 kilo-ohms.
The SN75LBC786 is available now from Texas Instruments and authorized distributors.
SN75LBC786 28-pin wide body SOIC $6.48
Suggested resale pricing in U.S. dollars per unit in 1K quantity.
