About project SlidePlayer Terms of Service. When this input is a logic 0and the counter is disabled, the counter will be cleared.
Are the data inputs, this is the data that can be load into the counter.
On every rising edge of clock, the output count is decremented by one. Note, LOAD signal goes low when the count is 2 These are enable inputs. This is the Borrow Output.

This signal is typically used to when the multiple counters are cascaded. Also, point out the all the clocks are tied together, that is why this is a synchronous counter design.
In this example 2, 1, 0, 15, 14, This is the clock input for the up counter. Thus, the Data Input will be loaded immediately.
When this 74lw163 is a logic 0and the counter is disabled, the counter will be cleared. Shown is the composite timing diagram for the 74LS counter. Share buttons are a little bit lower. For most free running counters, these input will be tied high. Published by Lester Phillips Modified over 3 years ago.

Project Lead The Way, Inc. This is the count of the counter. LOAD is an asynchronous input. Because the LOAD signal is a synchronous input, input data of 3 is not loaded until the next rising edge of the clock.
