SN75157P Datasheet | Texas Instruments

description The SN75157 is a dual differential line receiver designed to meet Standards EIA/TIA-422-B and -423-B and ITU V.10 and V.11. It utilizes Schottky circuitry and has TTL-patible outputs. The inputs are patible with either a single-ended or a differential-line system. The device operates from a single 5-V power supply and is supplied in 8-pin dual-in-line and small-outline packages. The SN75157 is characterized for operation from 0°C to 70°C. logic symbol† logic diagram (positive logic) 1IN + 1 1IN - 7 2IN + 6 2IN - 5 2 1OUT 3 2OUT † This symbol is in accordance with ANSI/IEEE Std 91-1984 and IEC Publication 617-12. 1 1IN + 1IN - 7 6 2IN + 2IN - 5 2 1OUT 3 2OUT Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
