Product Summary
The DS26LS32ACN is a quad differential line receiver, designed to meet the RS-422, RS-423 and Federal Standards 1020 and 1030 for balanced and unbalanced digital data transmission. The DS26LS32ACN has an input sensitivity of 200 mV over the input voltage range of ±7V. The device differ in function from the popular DS26LS32ACN 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, the device is available over the full military and commerical operating temperature ranges.
