When this input is a logic 0the data on the Data Input lines is loaded into the counter.

In this example a 12 is loaded. This signal is typically used to when the satasheet counters are cascaded. LOAD set to a logic 0 ; Outputs are loaded with input data on next rising edge of clock. The counter must first be disabled, then cleared. In this example a 12 is loaded. UP must be held at a logic 1. This is the clock input for the up counter.

It is a positive edge trigger clock. Provide an examples of a counter application implemented with the 74LS It is a positive edge trigger clock. Also, point out the all the clocks are tied together, that is why this is a synchronous counter design.

This is the count of the counter. On every rising edge of clock, the output count is incremented by one. This is the clock input. Katz Transparency No Chapter 7: DOWN must be held at a logic 1. For most free running counters, these input will be tied high.

Also, point out the all the clocks are tied together, that is why this is a synchronous counter design.

This is how dztasheet lower limit of the count is set. When this input is a logic 1the counter will be cleared.

Thus, the Data Output will be cleared immediately. This output is a logic 0 when the counter is at it lower when datasheeg counter is a down counter. If you wish to download it, please recommend it to your friends in any social system. Project Lead The Way, Inc. Thus, the Data Input will be loaded into the counter on the next rising edge of the clock when the LOAD input is a logic 0.

Daatasheet is the count of the counter. In this case13 Are the data inputs, this is the data that can be load into the counter. LOAD is an asynchronous input. This is the clear input.

For most free running counters, these input will be tied high. Note, LOAD signal goes low when the count is 2 The counter must first be disabled, then cleared.

ENT set to a logic 0 ; Counting is disabled.

Provide an examples of a counter application implemented with the 74LS ENT set to a logic 0 ; Counting is disabled. In datashet case13 This is the clear input. This is the clock input for the down counter. These are enable inputs.
