Description

The DS8925 is a dual driver/triple receiver device optimized to provide a single chip solution for a LocalTalk Interface.

The DS8925 device provides one differential TIA/EIA-422 driver, one TIA/EIA-423 single ended driver, one TIA/EIA422 receiver and two TIA/EIA-423 receivers, all in a surface mount 16 pin package. This device is electrically similar to the 26LS30 and 26LS32 devices.

The DS8925 drivers feature ±10V common mode range, and the differential driver provides TRI-STATEable outputs.

The DS8925 receivers offer ±200 mV thresholds over the ±10V common mode range.
