描述 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 has an input sensitivity of 500?mV over the input voltage range of ±15V. The DS26LS32A differs 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 commercial operating temperature ranges.特性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 All trademarks are the property of their respective owners.
