The enablefunction is common to all four receivers and offersa choice of active-high or active-low input. The3-state outputs permit connection direct to a bus-organized system. Fail-safe design ensures thatif the inputs are open, the outputs are always high.4A4YNCG3YNC–No internal connectionCompared to the AM26LS32 and the AM26LS33, the AM26LS32A and AM26LS33A incorporate an additionalstage of amplification to improve sensitivity. The input impedance has been increased resulting in less loadingof the bus line. The additional stage has increased propagation delay; however, this does not affectinterchangeability in most applications.The AM26LS32AC and AM26LS33AC are characterized for operation from 0°C to 70°C. The AM26LS32AMand AM26LS33AM are characterzed for operation over the full military temperature range of –55°C to 125°C.Please be aware that an important notice concerning availability, standard warranty, and use in critical applications ofTexasInstruments semiconductor products and disclaimers thereto appears at the end of this data sheet.AM26LS32 and AM26LS33 are trademarks of Advanced Micro Devices, Inc.PRODUCTION DATA information is current as of publication date.Products conform to specifications per the terms of Texas Instrumentsstandard warranty.
