具有使能端的 8 位等值/幅度比较器 (P=Q)
| Number of channels (#) | 8 |
| Technology Family | LS |
| Input type | Bipolar |
| Output type | Push-Pull |
| Features | High speed (tpd 10-50ns) |
- Compares Two-8-Bit Words
- Choice of Totem-Pole or Open-Collector Outputs
- Hysteresis at P and Q Inputs
- 'LS682 has 20-k
Pullup Resistors on the Q Inputs - SN74LS686 and 'LS687 … JT and NT 24-Pin, 300-Mil Packages
These magnitude comparators perform comparisons of two eight-bit binary or BCD words. All types provide P = Q\ outputs and all except 'LS688 provide P > Q\ outputs as well. The 'LS682, 'LS684, 'LS686, and 'LS688 have totem-pole outputs, while the 'LS685 and 'LS687 have open-collector outputs. The 'LS682 features 20-k pullup termination resistors on the Q inputs for analog or switch data.
