Synchronous Presettable Binary Counter
74AC161 • 74ACT161 Synchronous Presettable Binary Counter November 1988 Revised September 2003 74AC161 74ACT161 Synchronous Presettable Binary Counter General Description Features The AC/ACT161 are high-speed synchronous modulo-16I reduced by 50% CC binary counters. They are synchronously presettable for Synchronous counting and loading application in programmable dividers and have two types High-speed synchronous expansion of Count Enable inputs plus a Terminal Count output for Typical count rate of 125 MHz versatility in forming synchronous multistage counters. The AC/ACT161 has an asynchronous Master Reset input thatOutputs source/sink 24 mA overrides all other inputs and forces the outputs LOW. ACT161 has TTL-compatible inputs Ordering Code: Order Number Package Number Package Description 74AC161SC M16A 16-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150" Narrow 74AC161SJ M16D 16-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide 74AC161MTC MTC16 16-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide 74AC161PC N16E 16-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300" Wide 74ACT161SC M16A 16-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150" Narrow 74ACT161SJ M16D 16-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide 74ACT161MTC MTC16 16-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide 74ACT161PC N16E 16-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300" Wide Device also available in Tape and Reel.
