... MC74HC161A, MC74HC163A Presettable Counters High–Performance Silicon–Gate CMOS The MC74HC161A and HC163A are identical in pinout to the LS161 and LS163. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs. The HC161A and HC163A are programmable 4–bit binary counters with asynchronous and synchronous reset, respectively ...

... Q3 low MC74HC161A, MC74HC163A FUNCTION DESCRIPTION level. The HC161A resets asynchronously, and the HC163A resets with the rising edge of the Clock input (synchronous reset). Loading With the rising edge of the Clock, a low level on Load (Pin 9) loads the data from the Preset Data input pins (P0, P1, P2, P3) into the internal flip– ...
