1 / 7 page SN75146 DUAL DIFFERENTIAL LINE RECEIVER SLLS015B – FEBRUARY 1986 – REVISED MAY 1995 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D Meets or Exceeds the Requirements of ANSI EIA / TIA-422-B and -423-B D Meets or Exceeds the Requirements of ANSI EIA / TIA-232-E and ITU Recommendation V.28 With External Components D Meets Federal Standards 1020 and 1030 D Built-in 5-MHz Low-Pass Filter D Operates From Single 5-V Power Supply D Wide Common-Mode Voltage Range D High Input Impedance D TTL-Compatible Outputs D 8-Pin Dual-in-Line Package D Pinout Compatible With the µA9637 and µA9639 description The SN75146 is a dual differential line receiver designed to meet ANSI Standards EIA / TIA-422-B and -423-B. The receiver is designed to have a constant impedance with input voltages of ±3 V to ±25 V allowing it to meet the requirements of EIA / TIA-232-E and ITU recommendation V.28 with the addition of an external bias resistor. This receiver is designed for low-speed operation below 355 kHz and has a built-in 5-MHz low-pass filter to attenuate high-frequency noise. The inputs are compatible with either a single-ended or a differential line system and the outputs are TTL compatible. This device operates from a single 5-V power supply and is supplied in both the 8-pin dual-in-line and small-outline packages. The SN75146 is characterized for operation from 0 °C to 70°C. logic symbol† 5 6 7 8 2IN – 2IN + 1IN – 1IN + 2OUT 1OUT 3 2 † This symbol is in accordance with ANSI/IEEE Std 91-1984 and IEC Publication 617-12. logic diagram 2OUT 1OUT 5 6 7 8 2IN – 2IN + 1IN – 1IN + 3 2 Copyright © 1995, Texas Instruments Incorporated PRODUCTION DATA information is current as of publication date.
