The line receiver utilizes Schottky circuitry and has TTL-compatible outputs. The inputs are compatible with either a single-ended or a differential-line system. This device operates from a single 5-V power supply and is supplied in an 8-pin dual-in-line package or small-outline package. The uA9637AC is characterized for operation from 0°C to 70°C. logic symbol† logic diagram 8 1IN + 7 1IN – 6 2IN + 5 2IN – 2 1OUT 3 2OUT † This symbol is in accordance with ANSI/IEEE Std 91-1984 and IEC Publication 617-12. 8 1IN + 7 1IN – 6 2IN + 5 2IN – 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.

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTES: 1. All voltage values, except differential input voltage, are with respect to the network ground terminal. 2. Differential input voltage is measured at the noninverting input with respect to the corresponding inverting input.
