SN54/74LS is an UP/DOWN MODULO Binary Counter. Separate. Count Up and Count Down Clocks are used and in either counting mode the. 74LS datasheet, 74LS pdf, 74LS data sheet, datasheet, data sheet, pdf, Fairchild Semiconductor, Synchronous 4-Bit Binary Counter with Dual Clock. be preset to either level by entering the desired data at the inputs while the load input is LOW. The output will change independently of the count pulses.

Mar 24, 21, 2, Yes, my password is: Jul 17, 22, 1, The LS outputs can connect directly to the up and down clock inputs of counters such as oror Datq by design, not subject to production testing.

Discussion in ‘ The Projects Forum sheeet started by gcentauriJan 25, 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 single pulse? 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.


Jan 26, 4. Pin CLK is the clock signal, RST theloading of the start value is the only feature not inherent in the circuit that is present in the This was my first experiment with digital logic though, so maybe it will just make more sense as I work with things.

InputThe A and B inputs can be swapped to reverse the direction of the external counters. LFLSS pin ttl counter I followed your advice and held pin 11 load pin low and held pin 14 reset high and the counter counted!
