74LS161AM - Brand New MOTOROLA Counters / Dividers
-
Description
The 74LS161AM is a synchronous, presettable counter that belongs to the Counters / Dividers category of electronic components. It features an internal carry look-ahead for high-speed counting designs. With a 4-bit binary configuration, it utilizes a NOR gate to decode the carry output, preventing spikes during normal counting mode. Synchronous operation ensures all flip-flops are clocked simultaneously, eliminating output counting spikes associated with asynchronous counters. The 74LS161AM also includes a buffered clock input that triggers the four flip-flops on the rising edge of the clock input waveform.
