CD4024BC 7-Stage Ripple Carry Binary Counter October 1987 Revised April 2002 CD4024BC 7-Stage Ripple Carry Binary Counter General Description The CD4024BC is a 7-stage ripple-carry binary counter. Buffered outputs are externally available from stages 1 through 7. The counter is reset to its logical “0” stage by a logical “1” on the reset input. The counter is advanced one count on the negative transition of each clock pulse. Features s Wide supply voltage range: s Low power TTL compatibility: or 1 driving 74LS s High speed: 12 MHz (typ.) 3.0V to 15V Fan out of 2 driving 74L s High noise immunity: 0.45 VDD (typ.) input pulse rate VDD − VSS = 10V s Fully static operation Ordering Code: Order Number CD4024BCM CD4024BCN Package Number M14A N14A Package Description 14-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150" Narrow 14-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300" Wide Devices also available in Tape and Reel.
