26C31 Datasheet | Hitachi Semiconductor

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 m A. Features - TTL input patibility - 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 patible with HD26LS31 .sycelectronica..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 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 .sycelectronica..ar HD26C31 Absolute Maximum Ratings (Ta = 25°C) Item Symbol Ratings Unit Supply Voltage-...
