74HC193   4-Bit Up/Down Counters

74HC154 + 74HC193

74HC193 Description

The 74HC193 is a 4-bit synchronous binary up/down counter. Separate up/down clocks, CPU and CPD respectively, simplify operation. 

The outputs change state synchronously with the LOW-to-HIGH transition of either clock input. If the CPU clock is pulsed while CPD is held HIGH, the device will count up. If the CPD clock is pulsed while CPU is held HIGH, the device will count down. 

Only one clock input can be held HIGH at any time to guarantee predictable behavior. The device can be cleared at any time by the asynchronous master reset input (MR); it may also be loaded in parallel by activating the asynchronous parallel load input (PL). The terminal count up (TCU) and terminal count down (TCD) outputs are normally HIGH. 

When the circuit has reached the maximum count state of 15, the next HIGH-to-LOW transition of CPU will cause TCU to go LOW. TCU will stay LOW until CPU goes HIGH again, duplicating the count up clock. Likewise, the TCD output will go LOW when the circuit is in the zero state and the CPD goes LOW. The terminal count outputs can be used as the clock input signals to the next higher order circuit in a multistage counter, since they duplicate the clock waveforms. Multistage counters will not be fully synchronous, since there is a slight delay time difference added for each stage that is added. 

The counter may be preset by the asynchronous parallel load capability of the circuit. Information present on the parallel data inputs (D0 to D3) is loaded into the counter and appears on the outputs (Q0 to Q3) regardless of the conditions of the clock inputs when the parallel load (PL) input is LOW. A HIGH level on the master reset (MR) input will disable the parallel load gates, override both clock inputs and set all outputs (Q0 to Q3) LOW.

 If one of the clock inputs is LOW during and after a reset or load operation, the next LOW-to-HIGH transition of that clock will be interpreted as a legitimate signal and will be counted. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.

Frequently Asked Questions

1.What’s the difference between 74HC193 and 74HC191?

74HC191 and 74HC193 are both synchronous four-bit plus/minus engines, but the control function is slightly different. The 74HC193 can output borrow/carry bits but 74HC191 can not.

2.What’s the basic characteristics of the synchronous 4-bit up/down binary counter circuit in 74HC193?

1) Synchronous reversible 4-digit counter;
2) Asynchronous parallel load;
3) Asynchronous reset;
4) The expansion has no external logic.

3.How to design a hexadecimal counter with 74hc193?

Clearing method: When the counter counts to 0100 = 4, the TCU output is 0 at this time, this is the carry valid signal, because it is a synchronous counter, the counter will not be cleared until the next clock pulse arrives, and it is counting at this time To 0101, and it happens to be cleared. It can be cleared by connecting an inverter output to MR through TPU.
