高速 CMOS 逻辑可预设的同步 4 位二进制加/减计数器

The CD54/74HC190 are asynchronously presettable BCD decade counters, whereas the CD54/74HC191 and CD54/74HCT191 are asynchronously presettable binary counters.\n\n Presetting the counter to the number on preset data inputs (A–D) is accomplished by a low asynchronous parallel load (LOAD)\\ input. Cou • 2-V to 6-V VCC Operation (’HC190,191)\n• 4.5-V to 5.5-V VCC Operation (’HCT191)\n• Wide Operating Temperature Range of –55 to 125°C\n• Synchronous Counting and Asynchronous Loading\n• Two Outputs for n-Bit Cascading\n• Look-Ahead Carry for High-Speed Counting\n• Balanced Propagation Delay and Tran;
