AEIC-7272-S16

The AEIC-7272-S16 is a quad differential Line Driver IC with separate logic bias and driver bias pins. The tri-state output driver is pin compatible with 26LS31 in applications where pin 4 = 5V and pin 12 = GND. Internal clamp diodes allow trouble-free operation when driving cable lengths exceeding 100m. Split supplies are provided to minimize standby power dissipation in high voltage applications. The logic should be powered from a regulated 5V supply at the VCC-Bias pin. The output stages may then be powered by a separate supply at VCC-drivers, up to 30V. The outputs are protected against shorts to ground, shorts to VCC and to other outputs by a two-fold scheme of current limiting and thermal shutdown. This assures highly reliable operation in harsh environments.
