These devices offer optimum performance when used with the SN75LBC173 or SN75LBC175 quadruple line receivers. The SN65LBC174 and SN75LBC174 are available in the 16-terminal DIP package (N) and the 20-terminal wide-body small outline intergrated circuit (SOIC) package (DW). 16 2 15 3 14 4 13 5 12 6 11 7 10 8 9 VCC 4A 4Y 4Z 3,4EN 3Z 3Y 3A DW PACKAGE (TOP VIEW) description The SN65LBC174 and SN75LBC174 are monolithic, quadruple, differential line drivers with 3-state outputs. Both devices are designed to meet the requirements of the Electronics Industry Association Standard EIA-485. These devices are optimized for balanced multipoint bus transmission at data rates up to and exceeding 10 million bits per second. Each driver features wide positive and negative common-mode output voltage ranges, current limiting, and thermalshutdown protection, making it suitable for party-line applications in noisy environments. Both devices are designed using LinBiCMOS, facilitating ultralow power consumption and inherent robustness. 1 1 2 3 4 5 6 7 8 9 10 1A 1Y NC 1Z 1,2EN 2Z NC 2Y 2A GND 20 19 18 17 16 15 14 13 12 11 VCC 4A 4Y NC 4Z 3,4EN 3Z NC 3Y 3A NC – No internal connection FUNCTION TABLE (each driver) INPUT ENABLE H L X H H L H = high level, X = irrelevant, OUTPUTS Y Z H L Z L H Z L = low level, Z = high impedance (off) The SN75LBC174 is characterized for operation over the commercial temperature range of 0°C to 70°C.
