MC74F161A Datasheet (Motorola) - (MC74F161A / MC74F163A) SYNCHRONOUS PRESETTABLE BINARY COUNTER

MC74F161A, (MC74F161A / MC74F163A) SYNCHRONOUS PRESETTABLE BINARY COUNTER

The MC74F161A and MC74F163A count in modulo-16 binary sequence.

From state 15 (HHHH) they increment to state 0 (LLLL).

The clock inputs of all flip-flops are driven in parallel through a clock buffer.

Thus all changes of the Q outputs (except due to Master Reset of the MC74F161A) occur as a result o

SYNCHRONOUS PRESETTABLE BINARY COUNTER The MC74F161A and MC74F163A are high-speed synchronous modulo-16 binary counters.

They are synchronously presettable for application in programmable dividers and have two types of Count Enable inputs plus a Terminal Count output for versatility in forming synchronous multistage counters.

The MC74F161A has an asynchronous Master Reset input that overrides all other inputs and forces the outputs LOW.

The MC74F163A has a Synchronous Reset input that overrides
