They are pin-for-pin replacements for these earlier versions and will operate in their sockets. Performance enhancements include 10V/µs slew rate, 120k bits per second guaranteed transmission rate, and increased drive current for longer and more flexible cable configurations. Ease of use enhancements include smaller, 0.1µF charge pump capacitors, enhanced ESD protection, low power dissipation and overall ruggedized construction for commercial environments. The series is available in plastic and ceramic DIP and SOIC packages operating over the commercial, industrial and military temperature ranges.
