The ’HC161 devices 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.

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. The clear function for the ’HC161 devices 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 QA 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. 2 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 SCLS297D − JANUARY 1996 − REVISED SEPTEMBER 2003 logic diagram (positive logic) LOAD ENT ENP 9 10 15 LD† 7 RCO CK† CLK CLR A B C D 2 1 CK LD R M1 G2 1, 2T/1C3 G4 3D 4R 3 M1 G2 1, 2T/1C3 G4 3D 4R 4 M1 G2 1, 2T/1C3 G4 3D 4R 5 M1 G2 1, 2T/1C3 G4 3D 4R 6 14 13 12 11 QA QB QC QD † For simplicity, routing of complementary signals LD and CK is not shown on this overall logic diagram.

Load Circuit and Voltage Waveforms POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 9 SCLS297D − JANUARY 1996 − REVISED SEPTEMBER 2003 APPLICATION INFORMATION n-bit synchronous counters This application demonstrates how the look-ahead carry circuit can be used to implement a high-speed n-bit counter. The ’HC161 devices count in binary. Virtually any count mode (modulo-N, N1-to-N2, N1-to-maximum) can be used with this fast look-ahead circuit. The application circuit shown in Figure 2 is not valid for clock frequencies above 18 MHz (at 25°C and 4.5-V VCC). The reason for this is that there is a glitch that is produced on the second stage’s RCO and every succeeding stage’s RCO. This glitch is common to all HC vendors that Texas Instruments has evaluated, in addition to the bipolar equivalents (LS, ALS, AS). 10 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 SCLS297D − JANUARY 1996 − REVISED SEPTEMBER 2003 APPLICATION INFORMATION LSB CTR CT=0 M1 3CT=MAX G3 CLR Clear (L) LOAD ENT Count (H)/ Disable (L) ENP CLK RCO G4 C5/2,3,4+ Load (L) A 1,5D [1] QA Count (H)/ Disable (L) B [2] QB C [3] QC Clock D [4] QD CTR CT=0 M1 3CT=MAX G3 CLR LOAD ENT ENP CLK RCO G4 C5/2,3,4+ A 1,5D [1] QA B [2] QB C [3] QC D [4] QD CTR CT=0 M1 3CT=MAX G3 CLR LOAD ENT ENP CLK RCO G4 C5/2,3,4+ A 1,5D [1] QA B [2] QB C [3] QC D [4] QD CTR CT=0 M1 3CT=MAX G3 CLR LOAD ENT ENP CLK RCO G4 C5/2,3,4+ A 1,5D [1] QA B [2] QB C [3] QC D [4] QD To More−Significant Stages Figure 2 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 11 SCLS297D − JANUARY 1996 − REVISED SEPTEMBER 2003 APPLICATION INFORMATION The glitch on RCO is caused because the propagation delay of the rising edge of QA of the second stage is shorter than the propagation delay of the falling edge of ENT. RCO is the product of ENT, QA, QB, QC, and QD (ENT × QA × QB × QC × QD). The resulting glitch is about 7−12 ns in duration. Figure 3 shows the condition in which the glitch occurs. For simplicity, only two stages are being considered, but the results can be applied to other stages. QB, QC, and QD of the first and second stage are at logic one, and QA of both stages are at logic zero (1110 1110) after the first clock pulse. On the rising edge of the second clock pulse, QA and RCO of the first stage go high. On the rising edge of the third clock pulse, QA and RCO of the first stage return to a low level, and QA of the second stage goes to a high level. At this time, the glitch on RCO of the second stage appears because of the race condition inside the chip. 1 2 3 4 5 CLK ENT1 QB1, QC1, QD1 QA1 RCO1, ENT2 QB2, QC2, QD2 QA2 RCO2 Glitch (7−12 ns) Figure 3 The glitch causes a problem in the next stage (stage three) if the glitch is still present when the next rising clock edge appears (clock pulse 4). To ensure that this does not happen, the clock frequency must be less than the inverse of the sum of the clock-to-RCO propagation delay and the glitch duration (tg). In other words, fmax = 1/(tpd CLK-to-RCO + tg). For example, at 25°C at 4.5-V VCC, the clock-to-RCO propagation delay is 43 ns and the maximum duration of the glitch is 12 ns. Therefore, the maximum clock frequency that the cascaded counters can use is 18 MHz. The following tables contain the fclock, tw, and fmax specifications for applications that use more than two ’HC161 devices cascaded together. 12 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 SCLS297D − JANUARY 1996 − REVISED SEPTEMBER 2003 APPLICATION INFORMATION timing requirements over recommended operating free-air temperature range (unless otherwise noted) VCC fclock Clock frequency TA = 25°C MIN MAX Pulse duration, CLK high or low MIN MAX SN74HC161 MIN MAX 2V 3.6 2.5 2.9 4.5 V 18 12 14 6V tw SN54HC161 21 14 UNIT MHz 17 2V 140 200 170 4.5 V 28 40 36 6V 24 36 30 ns switching characteristics over recommended operating free-air temperature range, CL = 50 pF (unless otherwise noted) (see Note 4) PARAMETER FROM (INPUT) TO (OUTPUT) fmax VCC TA = 25°C MIN MAX SN54HC161 MIN MAX SN74HC161 MIN 2V 3.6 2.5 2.9 4.5 V 18 12 14 6V 21 14 17 MAX UNIT MHz NOTE 4: These limits apply only to applications that use more than two ’HC161 devices cascaded together. If the ’HC161 devices are used as a single unit, or only two cascaded together, then the maximum clock frequency that the device can use is not limited because of the glitch. In these situations, the device can be operated at the maximum specifications. A glitch can appear on RCO of a single ’HC161 device, depending on the relationship of ENT to CLK. Any application that uses RCO to drive any input except an ENT of another cascaded ’HC161 device must take this into consideration.
