DS34C86T Datasheet | National Semiconductor

Description The DS34C86T is a quad differential line receiver designed to meet the RS-422, RS-423, and Federal Standards 1020 and 1030 for balanced and unbalanced digital data transmission, while retaining the low power characteristics of CMOS. The DS34C86T has an input sensitivity of 200 m V over the mon mode input voltage range of ± 7V. Hysteresis is provided to improve noise margin and discourage output instability for slowly changing input waveforms. The DS34C86T features internal pull-up and pull-down resistors which prevent output oscillation on unused channels. Separate enable pins allow independent control of receiver pairs. The TRI-STATE ® outputs have 6 m A source and sink capability. The DS34C86T is pin patible with the DS3486.
