Dual Driver/Triple Receiver
General Description
The DS8925 is a dual driver/triple receiver device optimized
to provide a single chip solution for a LocalTalk Interface.
The device provides one differential TIA/EIA-422 driver, one
TIA/EIA-423 single ended driver, one TIA/EIA-422 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 drivers feature
鹵
10V common mode range, and the dif-
ferential driver provides TRI-STATEable outputs. The receiv-
ers offer
鹵
200 mV thresholds over the
鹵
10V common mode
range.
