| CD4043BC * CD4044BC Quad 3-STATE NOR R/S Latches * Quad 3-STATE NAND R/S Latches October 1987 Revised January 1999 CD4043BC * CD4044BC Quad 3-STATE NOR R/S Latches * Quad 3-STATE NAND R/S Latches General Description The CD4043BC are quad cross-couple 3-STATE CMOS NOR latches, and the CD4044BC are quad cross-couple 3STATE CMOS NAND latches. Each latch has a separate Q output and individual SET and RESET inputs. There is a common 3-STATE ENABLE input for all four latches. A logic "1" on the ENABLE input connects the latch states to the Q outputs. A logic "0" on the ENABLE input disconnects the latch states from the Q outputs resulting in an open circuit condition on the Q output. The 3-STATE feature allows common bussing of the outputs. Features s Wide supply voltage range: s Low power: 100 nW (typ.) s High noise immunity: 0.45 VDD (typ.) s Separate SET and RESET inputs for each latch s NOR and NAND configuration s 3-STATE output with common output enable 3V to 15V Applications * Multiple bus storage * Strobed register * Four bits of independent storage with output enable * General digital logic Ordering Code: Order Number CD4043BCM CD4043BCN CD4044BCM CD4044BCSJ CD4044BCN Package Number M16A N16E M16A M16D N16E Package Description 16-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150" Narrow Body 16-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300" Wide 16-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150" Narrow Body 16-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide 16-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300" Wide Devices also available in Tape and Reel.
