Part Details:

74F161A, April 2007 74F163A Sync 74F161A, 74F163A tm Synchronous Presettable Binary Counter Features General Description Synchronous counting and loading The 74F161A and 74F163A are high-speed synchro-nous modulo-16 binary counters. They are synchro- hr High-speed synchronous expansion nously presettable for application in programmable onous Presettab Typical count frequency of 120MHz dividers and have two types of Count Enable inputs plusa Terminal Count output for versatility in formingsynchronous multi-stage counters. The 74F161A has anasynchronous Master-Reset input that overrides all otherinputs and forces the outputs LOW. The 74F163A has aSynchronous Reset input that overrides counting andparallel loading and allows the outputs to be simulta-neously reset on the rising edge of the clock. The le Binar 74F161A and 74F163A are high-speed versions of the74F161 and 74F163. y Counter Ordering Information Order Package Number Number Package Description 74F161ASC M16A 16-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150" Narrow 74F161ASJ M16D 16-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide 74F161APC N16E 16-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300" Wide 74F163ASC M16A 16-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150" Narrow 74F163ASJ M16D 16-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide 74F163APC N16E 16-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300" Wide Device also available in Tape and Reel.
