74LS192 (hay IC 74192) thuộc họ IC 74xx là một bộ đếm BCD thập phân lên xuống. Các đồng hồ đếm riêng biệt được dùng ở cả 2 chế độ đếm lên xuống, các mạch hoạt động một cách đồng bộ. Đầu ra sẽ thay đổi trạng thái đồng bộ với các chuyển đổi từ thấp đến cao trên các đầu vào đồng hồ. Tìm hiểu IC 74LS192 là gì?

2023年10月27日 · What is IC 74192? The IC 74192 is a integrated circuit (IC) that is commonly used as a 4-bit up/down decade counter. The 74192 is a synchronous counter, which means that it counts in sync with an external clock signal, and it …

Order today, ships today. 74192PC – Counter IC Counter, Decade 1 Element 4 Bit Positive Edge 16-PDIP from Fairchild Semiconductor. Pricing and Availability on millions of electronic components from Digi-Key Electronics.

The SN54/74LS192 is an UP/DOWN BCD Decade (8421) Counter and the SN54/74LS193 is an UP/DOWN MODULO-16 Binary Counter. Separate Count Up and Count Down Clocks are used and in either counting mode the circuits operate synchronously. The outputs change state synchronous with the LOW-to-HIGH transitions on the clock inputs.

2010年6月30日 · You may have a major problem feeding a TTL signal to a CMOS IC. CMOS usually needs its inputs to go to Vcc, and TTL can't do that. Use a CD4510 for the up/down counter, and your problems may be over, after you figure out the different pinout.

DESCRIPTION The M54/74HC192/193 are ahigh speed CMOSSYNCHRONOUS UP/DOWN DECADE COUNTERS fabricated in silicon gate C2MOS technology. They have the same high speed performance of LSTTL combined with true CMOS low power consumption. The counter has two separate clock inputs, an UP COUNT input and a DOWN COUNT input.

2015年11月5日 · I have to build a clock timer using 74192. MM:SS clock where it should count 59:59. But when I am setting the clock, it count until 7 and goes back to 5. And at the time 00:00 it resets which should not happened. Please help! Your video is just about useless.
