+5V Powered RS-232 Transmitters/Receivers
The drivers feature true TTL/CMOS input compatibility, slew­rate-limited output, and 300Ω power-off source impedance. The receivers can handle up to ±30V, and have a 3kΩ to 7kΩ input impedance. The receivers also feature hysteresis to greatly improve noise rejection.
File Number 3138.7
