CD4514BC • CD4515BC 4-Bit Latched/4-to-16 Line Decoders CD4514BC • CD4515BC 4-Bit Latched/4-to-16 Line Decoders The CD4514BC and CD4515BC are 4-to-16 line decoders with latched inputs implemented with complementary MOS CMOS circuits constructed with N- and P-channel enhancement mode transistors. These circuits are primarily used in decoding applications where low power dissipation and/or high noise immunity is required. The CD4514BC output active high option presents a logical “1” at the selected output, whereas the CD4515BC presents a logical “0” at the selected output. The input latches are type flip-flops, which hold the last input data presented prior to the strobe transition from “1” to This input data is decoded and the corresponding output is activated. An output inhibit line is also available. s Wide supply voltage range 3.0V to 15V s High noise immunity VDD typ. s Low power TTL fan out of 2 compatibility driving 74L s Low quiescent power dissipation: µW/package VDC s Single supply operation s Input impedance = typically s Plug-in replacement for MC14514, MC14515 Ordering Code: Order Number Package Number Package Diagram CD4514BCWM M24B 24-Lead Small Outline Integrated Circuit SOIC , JEDEC MS-013, Wide CD4514BCN N24A 24-Lead Plastic Dual-In-Line Package PDIP , JEDEC MS-011, Wide CD4515BCWM Note 1 M24B 24-Lead Small Outline Integrated Circuit SOIC , JEDEC MS-013, Wide CD4515BCN N24A 24-Lead Plastic Dual-In-Line Package PDIP , JEDEC MS-011, Wide Note 1 Devices also available in Tape and Reel.

Except for “Operating Temperature Range” they are not meant to imply that the devices should be operated at these limits. The tables of “Recommended Operating Conditions” and “Electrical Characteristics” provide conditions for actual device operation. Note 3 VSS = 0V unless otherwise specified.
