Overview

4-STAGE SYNCHRONOUS BIDIRECTIONAL COUNTERS The MC54/74F168 and MC54/74F169 are fully synchronous 4-stage up/ down counters.
The F168 is a BCD decade counter; the F169 is a modulo-16 binary counter.
Both feature a preset capability for programmable operation, carry lookahead for easy cascading, and a U/D input to control the direction of counting.
All state changes, whether in counting or parallel loading, are initiated by the LOW-to-HIGH transition of the clock.
• Asynchronous Counting and Loading • Built-In Lookahead Carry Capability • Presettable for Programmable Operation CONNECTION DIAGRAM (TOP VIEW) VCC 16 TC 15 Q0 14 Q1 13 Q2 12 Q3 11 CET 10 PE 9 16 MC54/74F168 MC54/74F169 4-STAGE SY...
