AEIC-7273-S16

AEIC-7273-S16 Quad Differential Line Driver LC With Open-Collector Outputs And Enable Function Data Sheet Description Features These line drivers are similar in function to the AEIC7272-S16, only in an open-collector format. The VCC pin powers the internal logic only. Output voltage is dependent on the customer supplied voltage, up to a maximum of 30 V. There is essentially no difference in output swing or performance with VCC (LOGIC) values from 3.5-30 V. Internal clamp diodes allow trouble-free operation when driving cable lengths exceeding 100 meters. The outputs are protected by initiating shutdown when junction temperatures exceed safe limits. This feature assures highly reliable operation in harsh environments. Heat sinking is aided by having pin 8 directly connected to the ASIC substrate inside the package.  Supply (Bias) Voltage Range 3.5 V to 30 V  Operation to 800KHz  CMOS and TTL Compatible Inputs  Support RS422A  High Impedance Buffered Inputs with hysteresis  NPN Open-Collector outputs  80 mA peak SINK/SOURCE current  Outputs Protected by Thermal Shut-Down Pin Assignment This part is available in 16L SOIC Pb-free) package.
