Am26LS32/Am26LS33 Quad Differential Line Receivers on 51-880 cl s Advanced Micro Devices DISTINCTIVE CHARACTERISTICS mM Input voltage range of 15 V (differential or common mode) on Am26LS33; 7 V (differential or common mode) on Am26LS32 ~ 200 mV sensitivity over the input voltage range on Am26LS32; 500 mV sensitivity on Am26LS33 @ 66k minimum input impedance with 30 mV input hysteresis M@ The Am26LS32 meets all the requirements of RS-422 and RS-423 = 6Operation from single +5 V supply m= Fail safe input-output relationship. Output always high when inputs are open m@ Three-state drive, with choice of complementary output enables, for receiving directly onto a data bus GENERAL DESCRIPTION The Am26LS32 is a quad line receiver designed to meet the requirements of RS-422 and RS-423, and Federal Standards 1020 and 1030 for balanced and unbalanced digital data transmission. The Am26LS32 features an input sensitivity of 200 mV over the input voltage range of +7 V. The Am26LS33 features an input sensitivity of 500 mV over the input voltage range of +15 V. The Am26LS32 and Am26LS33 provide an enable and disable function common to all four receivers. Both parts feature 3-state outputs with 8 mA sink capability and in- corporate a fail safe input-output relationship which keeps the outputs high when the inputs are open. The Am26LS32 and Am26LS33 are constructed using Advanced Low-Power Schottky processing. BLOCK DIAGRAM ENABLE ENABLE IND. IND INc+ INc- INg. INB- INa.
