Channels are paired for differential 3-channel operation by a high signal at the DIFF input, providing differential output signals for the three inputs E1, E3 and E5. All inputs are patible with CMOS and TTL levels. The push-pull output stages have a driver power of typically 200 m A from 24 V and are short-circuitproof and current-limited, shutting down with excessive temperature. For bus applications the output stages can be switched to high impedance using input ENA. i C-DL monitors supply voltages VB and VCC and the...
