POLARITY_REVERSING_DRIVE

Half of 9614 polarity-reversing line driver feeds Hewlett-Packard HCPL-2602 optically coupled line receiver through shielded、twisted-pair、or coax cable. Data rate is improved considerably by using Schottky diode at input of receiver. Best data rates are achieved when tPHL (propagation delay time to low output level) and tPLH (propagation delay time to high output level) are closest to being equal，－ Optoelectronics Designer's Catalog 1977, Hewlett-Packard, Palo Alto, GA, 1977、p 158－159.
