74ABT377 Octal D-Type Flip-Flop with Clock Enable 74ABT377 Octal D-Type Flip-Flop with Clock Enable The ABT377 has eight edge-triggered, D-type flip-flops with individual D inputs and Q outputs. The common buffered Clock CP input loads all flip-flops simultaneously when the Clock Enable CE is LOW. The register is fully edge-triggered. The state of each D input, one setup time before the LOW-to-HIGH clock transition, is transferred to the corresponding flip-flop’s Q output. The CE input must be stable only one setup time prior to the LOW-to-HIGH clock transition for predictable operation. s Clock enable for address and data synchronization applications s Eight edge-triggered D-type flip-flops s Buffered common clock s See ABT273 for master reset version s See ABT373 for transparent latch version s See ABT374 for 3-STATE version s Output sink capability of 64 mA, source capability of 32 mA s Guaranteed latchup protection s High impedance glitch free bus loading during entire power up and power down cycle s Non-destructive hot insertion capability s Disable time less than enable time to avoid bus contention Ordering Code: Order Number Package Number Package Description 74ABT377CSC M20B 20-Lead Small Outline Integrated Circuit SOIC , JEDEC MS-013, Wide Body 74ABT377CSJ M20D 20-Lead Small Outline Package SOP , EIAJ TYPE II, 5.3mm Wide 74ABT377CMSA MSA20 20-Lead Shrink Small Outline Package SSOP , EIAJ TYPE II, 5.3mm Wide 74ABT377CMTC MTC20 20-Lead Thin Shrink Small Outline Package TSSOP , JEDEC MO-153, 4.4mm Wide Devices also available in Tape and Reel.
