Texas Instruments SN75154N
The SN75154 is a monolithic low-power Schottky line receiver designed to satisfy the requirements of the standard interface between data terminal equipment and data communication equipment as defined by ANSI Standard EIA/TIA-232-E. The output is compatible with most TTL circuits when either supply voltage is used.SN75154 QUADRUPLE LINE RECEIVER D Meets or Exceeds the Requirements of ANSI Standard EIA/TIA-232-E and ITU Recommendation V.28 D Input Resistance . . . 3 kΩ to 7 kΩ Over Full EIA/TIA-232-E Voltage Range D Input Threshold Adjustable to Meet Fail-Safe Requirements Without Using External Components D Built-In Hysteresis for Increased Noise Immunity D Inverting Output Compatible With TTL D Output With Active Pullup for Symmetrical Switching Speeds D Standard Supply Voltages . . . 5 V or 12 V SLLS083B – NOVEMBER 1970 – REVISED MAY 1995 D OR N PACKAGE (TOP VIEW) 3T 1 2T 2 1T 3 1A 4 2A 5 3A 6 4A 7 GND 8 16 VCC2 15 VCC1 14 4T 13 1Y 12 2Y 11 3Y 10 4Y 9 R1† † For function of R1, see schematic description Other applications are for relatively short, single-line, point-to-point data transmission and for level translators. Operation is normally from a single 5-V supply; however, a built-in option allows operation from a 12-V supply without the use of additional components. In normal operation, the threshold-control terminals are connected to the VCC1 terminal, even if power is being supplied via the alternate VCC2 terminal.
