Philips Semiconductors - PIP - 74HC/HCT193; Presettable synchronous 4-bit binary up/down counter
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.
