The SN74LS161 4-bitbinary counters. The carry output is decoded by means ofa NOR gate, thus preventing spikes during the normalcounting mode of operation.
This mode of operation eliminates the output countingspikes which are normally associated with asynchronous(ripple clock) counters. A buffered clock input triggers thefour flip-flops on the rising (positive-going) edge of theclock input waveform.
Maximum High Level Output Current (mA): -0.4
Minimum Operating Supply Voltage (V): 4.75
Typical Operating Supply Voltage (V): 5
Maximum Operating Supply Voltage (V): 5.25
Operating Temperature: 0 °C~+70 °C
