Quad Differential Line Receivers
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.
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
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
