Binary Synchronous Counter, 32 MHz, 4.75 V to 5.25 V, DIP-16 Product Overview The SN74LS161AN is a 4-bit Synchronous Binary Counter features an internal carry look-ahead for application in high-speed counting designs. Synchronous operation is provided by having all flip-flops clocked simultaneously so that the outputs change coincident with each other when so instructed by the count-enable inputs and internal gating. This mode of operation eliminates the output counting spikes that are normally associated with asynchronous (ripple clock) counters, however counting spikes may occur on the (RCO) ripple carry output. A buffered clock input triggers the four flip-flops on the rising edge of the clock input waveform. This counter is fully programmable, that is, the outputs may be preset to either level. As presetting is synchronous, setting up a low level at the load input disables the counter and causes the outputs to agree with the setup data after the next clock pulse regardless of the levels of the enable inputs. Internal look-ahead for fast counting Carry output for n-bit cascading Synchronous counting Synchronously programmable Load control line Diode-clamped inputs Applications Industrial Product Information Logic Family / Base Number: 74LS161 Counter Type: Binary Clock Frequency: 32MHz Count Maximum: 15 Logic Case Style: DIP No. of Pins: 16Pins Supply Voltage Min: 4.75V Supply Voltage Max: 5.25V Logic IC Family: 74LS Logic IC Base Number: 74161 Operating Temperature Min: 0°C Operating Temperature Max: 70°C Product Range: - MSL: -
