XL14514 – 4-to-16 Line Decoder / Demultiplexer – Xinluda

About this part

The Xinluda XL14514 (also cataloged under the XD14514 designation) is a CMOS 4-bit strobed-latch combined with a 4-to-16 line decoder/demultiplexer. It belongs to the industry-standard CD4514 / MC14514 family, providing one-of-sixteen active-high output decoding from a 4-bit binary input, with on-chip input latches that hold the last data present before the Latch Enable (strobe) transitions. An inhibit/enable control allows all outputs to be held low, and the device can also operate as a 1-to-16 demultiplexer by routing data through the enable input while the address lines select the target output.

Built on complementary N- and P-channel enhancement-mode MOS transistors, the XL14514 offers wide-supply flexibility, high noise immunity, and very low quiescent power that have made the 4514 a long-running standard in address decoding, keyboard scanning, and control-line selection. Xinluda specifies the device over a 3 V to 18 V supply range. The part is supplied in a through-hole DIP-24 package, making it convenient for legacy boards, repair/retrofit work, and education or prototyping applications.

Key Features

• 4-bit strobed input latch plus 4-to-16 line decoder in a single device (CD4514 / MC14514 compatible)
• 16 decoded outputs, active-high (one selected output per 4-bit address)
• Input latches hold the last data before the Latch Enable (strobe) transition
• Inhibit/Enable control holds all outputs low when asserted
• Usable as a 1-to-16 demultiplexer via the enable input
• Wide CMOS operating supply range of 3 V to 18 V, with high noise immunity and very low standby power
• Through-hole DIP-24 package

Detailed electrical limits (propagation delay, output drive, timing) should be confirmed against the linked Xinluda datasheet for your specific operating conditions.

Applications

• Address decoding and memory/peripheral chip selection
• 1-of-16 control-line or relay selection
• Keyboard and switch-matrix scanning
• Display and indicator (LED) multiplexing
• Hexadecimal / BCD decoding and program-counter decoding
• Legacy board repair and retrofit of CD4514 / MC14514 / 74HC4514 sockets

Why Source XL14514 from Pacific Component Xchange

The Xinluda XL14514 is a specialty CMOS logic device with limited authorized-distributor availability, which makes it exactly the kind of hard-to-find part Pacific Component Xchange is built to source. As an independent distributor, we locate obsolete, allocated, and low-availability components across a vetted global supply network. Every order is backed by our authenticity and counterfeit-avoidance process, and we ship worldwide to support production, maintenance, and end-of-life sustainment needs.
