This circuit is a synchronous up down 4-bit binary counter. Synchronous operation is provided by having all flip-flops clocked simultaneously so that the outputs. 74LS datasheet, 74LS pdf, 74LS data sheet, datasheet, data sheet, pdf, Fairchild Semiconductor, Synchronous 4-Bit Binary Counter with Dual Clock. SN54/74LS is an UP/DOWN MODULO Binary Counter. Separate. Count Up and Count Down Clocks are used and in either counting mode the.

This IC is a discontinue item. I followed your advice and held pin 11 load pin low and held pin 14 reset high and the counter counted!
Any help would datasehet great.
A Tale of 3 Smart Cities: Potentiometer Questions Started by norbss Yesterday at My best guess is that the pulse is too slow, but even when I apply datasheett Hz square wave nothing happens.

Confirm that 5V power is present on the Power pin pin 16 and ground is present on pin 8. Do you already have an account?
Often there is a timing diagram that contains the same information along with the critical timing information as well. Datasheets, Manuals or Parts.

Replacement Transformer Started by ncag Today at 7: I’d would not go with the because it counts in binary. The count-down terminal is held high. Your name or email address: Hardware, Tools, and Toolchain This is Part 1 of a step-by-step guide to bringing custom microcontroller designs to life. Welcome to our site!
So my first project has been to try and make a 7-segment display count up from 0 to 9 using some kind of button press. Jan 26, 2.
When I flip the switch I know I’m getting a slow pulse maybe that’s the problem, and if so, is there a circuit I can build to make a quick dattasheet pulse? Jan 26, 9.

Click here to register now. Do you have LOAD pin 11 held high? Terminal count up pin 12 connects to ci pulse up pin 5 of the next stage.
Mar 24, 21, 2, Right now Datsaheet have a chip debouncing a switch and and output from that going into the count-up terminal of the Jan 28, 9, I’m wondering if I’m not sending it a pulse that it can recognize as a clock cycle, or if there’s just something weird with the chip.
