description

These synchronous, presettable counters feature

an internal carry look-ahead for application in

high-speed counting designs. The ’HC161 are

4-bit binary counters. 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 (ENP, ENT) inputs and internal

gating. This mode of operation eliminates the

output counting spikes that are normally

associated with synchronous (ripple-clock)

counters. A buffered clock (CLK) input triggers the

four flip-flops on the rising (positive-going) edge of

the clock waveform.

These counters are fully programmable; that is,

they can be preset to any number between 0 and

9 or 15. 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.

NC – No internal connection

The clear function for the ’HC161 is asynchronous. A low level at the clear (CLR) input sets all four of the flip-flop

outputs low, regardless of the levels of the CLK, load (LOAD), or enable inputs.

The carry look-ahead circuitry provides for cascading counters for n-bit synchronous applications without

additional gating. Instrumental in accomplishing this function are ENP, ENT, and a ripple-carry output (RCO).

Both ENP and ENT must be high to count, and ENT is fed forward to enable RCO. Enabling RCO produces a

high-level pulse while the count is maximum (9 or 15 with Q high). This high-level overflow ripple-carry pulse

can be used to enable successive cascaded stages. Transitions at ENP or ENT are allowed, regardless of the

level of CLK.

These counters feature a fully independent clock circuit. Changes at control inputs (ENP, ENT, or LOAD) that

modify the operating mode have no effect on the contents of the counter until clocking occurs. The function of

the counter (whether enabled, disabled, loading, or counting) is dictated solely by the conditions meeting the

stable setup and hold times.

The SN54HC161 is characterized for operation over the full military temperature range of –55°C to 125°C. The

SN74HC161 is characterized for operation from –40°C to 85°C.
