74HC193; 74HCT193

Presettable synchronous 4-bit binary up/down counter

Rev. 4 — 24 June 2013

Product data sheet

1. General description

The 74HC193; 74HCT193 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 behaviour. 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 V
