4.13.3.2 Wiring the Differential Input Terminals
The direct-current signals ranging in voltage from 5 V to 24 V can pass through the high-speed input terminals
X0.0+~X0.1+, X0.0-~X0.1-, X0.8+~X0.11+, and X0.8-~X0.11- on AH02HC-5A, and the high-speed input
terminals X0.0+~X0.3+, X0.0-~X0.3-, X0.8+~X0.15+, and X0.8-~X0.15- on AH04HC-5A. The frequency of
input signals can be up to 200 kHz. These high-speed input terminals are connected to a differential (two-wire)
line driver.
