General Description
●The DS26LS32 and DS26LS32A are quad differential line receivers designed to meet the RS-422, RS-423 and Federal Standards 1020 and 1030 for balanced and unbalanced digital data transmission.
●The DS26LS32 and DS26LS32A have an input sensitivity of 200 mV over the input voltage range of ±7V and the DS26LS33 have an input sensitivity of 500 mV over the input voltage range of ±15V.
●The DS26LS32A differ in function from the popular DS26LS32 and DS26LS33 in that input pull-up and pull-down resistors are included which prevent output oscillation on unused channels.
●Each version provides an enable and disable function common to all four receivers and features TRI-STATE ® outputs with 8 mA sink capability. Constructed using low power Schottky processing, these devices are available over the full military and commerical operating temperature ranges.
●Features
●■ High differential or common-mode input voltage ranges of ±7V on the DS26LS32 and DS26LS32A and ±15V on the DS26LS33
●■ ±0.2V sensitivity over the input voltage range on the DS26LS32 and DS26LS32A, ±0.5V sensitivity on the DS26LS33
●■ DS26LS32 and DS26LS32A meet all requirements of RS-422 and RS-423
●■ 6k minimum input impedance
●■ 100 mV input hysteresis on the DS26LS32 and DS26LS32A, 200 mV on the DS26LS33
●■ Operation from a single 5V supply
●■ TRI-STATE outputs, with choice of complementary output enables for receiving directly onto a data bus
