HIN232A high-speed RS - 232 transmitter/receiver interface circuit meets all ElA high-speed RS - 232 - e and v. 28 specifications, and is especially suitable for the application of 12V is not available. They require a +5V power supply and are equipped with an on-board charging pump voltage converter to generate a +10V and -10V power supply from the 5V power supply.
Universal test circuit
Power supply resistance configuration
The driver has a true TTL/CMOS input compatibility, conversion rate limit output impedance and 300 off power. The receiver can handle up to 30V input, and there are 3k to 7 k input impedance. The receiver also has hysteresis to greatly improve noise suppression.
