Part Details:

74AC November 1988 Revised November 1999 169 4- Stage 74AC1694-Stage Synchronous Bidirectional Counter Synchr General Description Features The AC169 is fully synchronous 4-stage up/down counter. s ICC reduced by 50% The AC169 is a modulo-16 binary counter. It features a s Synchronous counting and loading onous preset capability for programmable operation, carry looka- s head for easy cascading and a U/D input to control the Built-In lookahead carry capability direction of counting. All state changes, whether in count- s Presettable for programmable operation ing or parallel loading, are initiated by the LOW-to-HIGH s Outputs source/sink 24 mA B transition of the Clock. idi rect Ordering Code: ional Order Number Package Number Package Description 74AC169SC M16A 16-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150" Narrow Body 74AC169SJ M16D 16-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide Co 74AC169MTC MTC16 16-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide unter 74AC169PC N16E 16-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300" Wide Device also available in Tape and Reel.
