1 / 8 page © Semiconductor Components Industries, LLC, 1999 December, 1999 – Rev. 6 1 Publication Order Number: SN74LS682/D SN74LS682 SN74LS684 SN74LS688 8-Bit Magnitude Comparators The SN74LS682, 684, 688 are 8-bit magnitude comparators. These device types are designed to perform comparisons between two eight-bit binary or BCD words. All device types provide P = Q outputs and the LS682 and LS684 have P > Q outputs also. The LS682, LS684 and LS688 are totem pole devices. The LS682 has a 20 k Ω pullup resistor on the Q inputs for analog or switch data. OUTPUT OUTPUT TYPE P = Q P > Q ENABLE CONFIGURATION PULLUP LS682 yes yes no totem-pole yes LS684 yes yes no totem-pole no LS688 yes no yes totem-pole no GUARANTEED OPERATING RANGES Symbol Parameter Min Typ Max Unit VCC Supply Voltage 4.75 5.0 5.25 V TA Operating Ambient Temperature Range 0 25 70 °C IOH Output Current – High – 0.4 mA IOL Output Current – Low 24 mA LOW POWER SCHOTTKY Device Package Shipping ORDERING INFORMATION SN74LS682N 16 Pin DIP 1440 Units/Box SN74LS682DW 16 Pin SOIC DW SUFFIX CASE 751D http://onsemi.com 2500/Tape & Reel PLASTIC N SUFFIX CASE 738 20 1 20 1 SN74LS684N 16 Pin DIP 1440 Units/Box SN74LS684DW 16 Pin 2500/Tape & Reel SN74LS688N 16 Pin DIP 1440 Units/Box SN74LS688DW 16 Pin 2500/Tape & Reel |
