LTC1321/LTC1322/LTC1335

TYPICAL APPLICATI S

The LTC1322/LTC1335 can be used to translate EIA562 to

RS422 interface level or vice versa as shown in Figure 22.

One port is configured as EIA562 transceiver and the other

as RS485 transceiver. The LTC1322 can also support

RS232 to RS422 level translation if VDD is between 6.5V

and 10V, and VEE is between – 6.5V and – 10V.

Using two LTC1321/LTC1335 as level translators, the

EIA562/RS232 interface distance can be extended to 4000

feet with twisted wires (Figure 23).
