DS34C86TM

CMOS 差动线路接收器

The is a quad CMOS 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 200mV over the common 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 6mA source and sink capability. The DS34C86T is pin compatible with the DS3486.
