26C31-SMD Quadruple Differential Line Drivers With 3 State Outputs ADE-205-574 (Z) 1st. Edition Dec. 2000 Description The HD26C31 features quadruple differential line drivers which satisfy the requirements of EIA standard RS-422A. This device is designed to provide differential signals with high current capability on bus lines. The circuit provides enable input to control all four drivers. The output circuit has active pull up and pull down and is capable of sinking or sourcing 20 mA. Features TTL input compatibility Propagation delay time: 6 ns typ Output to output skew: 0.5 ns typ High output impedance in power off conditions Meets EIA standard RS-422A Operates from a single 5 V supply Three state outputs Low power dissipation with CMOS process Power up and power down protection Pin to pin compatible with HD26LS31 www.sycelectronica.com.ar HD26C31 Pin Arrangement 1A 1 1Y 2 1Z 3 Enable G 4 2Z 5 2Y 6 2A 7 GND 8 16 VCC 15 4A 14 4Y 13 4Z 12 Enable G 11 3Z 10 3Y 9 3A (Top view) Function Table Input Enables AG HH LH HX LX XL H : High level L : Low level X : Irrelevant Z : High impedance G X X L L H Outputs Y H L H L Z Z L H L H Z 2 www.sycelectronica.com.ar HD26C31 Absolute Maximum Ratings (Ta = 25°C) Item Symbol Ratings Unit Supply Voltage*2 VCC –0.5 to 7.0 V Input Voltage VIN –1.5 to VCC +1.5 V Output Voltage VOUT –0.5 to VCC +0.5 V Power Dissipation Storage Temperature Range PT Tstg 500 –65 to 150 mW °C Lead Temperatur...
