Description
CD4514BC * CD4515BC 4-Bit Latched/4-to-16 Line Decoders October 1987 Revised January 2004 CD4514BC * CD4515BC 4-Bit Latched/4-to-16 .
The CD4514BC and CD4515BC are 4-to-16 line decoders with latched inputs implemented with complementary MOS (CMOS) circuits constructed with N- and P-c.
Features
* s Wide supply voltage range: 3.0V to 15V s High noise immunity: 0.45 VDD (typ. ) s Low power TTL: fan out of 2
compatibility: driving 74L s Low quiescent power dissipation:
0.025 µW/package @ 5.0 VDC s Single supply operation
s Input impedance = 1012Ω typically s Plug-in replacement for MC14514, MC14
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 R
* S type flip-flops, which hold the last input
