Part Details:

74AC June 1988 Revised October 2000 399 · 74ACT399 74AC399 · 74ACT399Quad 2-Port Register General Description Features Q The AC/ACT399 is the logical equivalent of a quad 2-input s ICC reduced by 50% u multiplexer feeding into four edge-triggered flip-flops. A s Select inputs from two data sources a common Select input determines which of the two 4-bit d s Fully positive edge-triggered operation 2- words is accepted. The selected data enters the flip-flop onthe rising edge of the clock. s Outputs source/sink 24 mA Port s AC/ACT399 has TTL-compatible inputs Regi Ordering Code: ster Order Number Package Number Package Description 74AC399SC M16A 16-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150 Narrow 74AC399PC N16E 16-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300 Wide 74ACT399SC M16A 16-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150 Narrow 74ACT399SJ M16D 16-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide 74ACT399MTC MTC16 16-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide 74ACT399PC N16E 16-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300 Wide Device also available in Tape and Reel.
