DS26LS33M Datasheet | National Semiconductor

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 m V over the input voltage range of ± 7V and the DS26LS33 have an input sensitivity of 500 m V over the input voltage range of ± 15V. The DS26LS32A differ in function from the popular DS26LS32 and DS26LS33 in that input pull-up and pulldown resistors are included which prevent output oscillation on unused channels. Each version provides an enable and disable function mon to all four receivers and features TRI-STATE ® outputs with 8 m A sink capability. Constructed using low power Schottky processing, these devices are available over the full military and merical operating temperature ranges. Features n High differential or mon-mode input voltage ranges of ± 7V on the DS26LS32 and DS26LS32A and ± 15V on the DS26LS33 n ± 0.2V sensitivity over the input voltage range on the DS26LS32 and DS26LS32A, ± 0.5V sensitivity on the DS26LS33 n DS26LS32 and DS26LS32A meet all requirements of RS-422 and RS-423 n 6k minimum input impedance n 100 m V input hysteresis on the DS26LS32 and DS26LS32A, 200 m V on the DS26LS33 n Operation from a single 5V supply n TRI-STATE outputs, with choice of plementary output enables for receiving directly onto a data bus Logic Diagram F w C ww DS005255 r e .n a ua TRI-STATE ® is a registered trademark of National Semiconductor Corporation. © 2004 National Semiconductor Corporation t e n ce. .national. 8 c T om ria l http://..
