What are the key features of CD74HC259E?
- 8-bit addressable D-latch with integrated 1:8 demultiplexer reducing output port expansion to a single IC
- HC CMOS family operating from 2 V to 6 V with 5.2 mA output sink current per channel
- 16-pin DIP through-hole package for easy breadboard prototyping and robust industrial panel PCB assembly
What is CD74HC259E used for?
The CD74HC259E is used in microcontroller output expansion circuits where a single 3-bit address bus can drive 8 independently latched GPIO lines without consuming additional MCU pins. Its 1:8 demultiplexer architecture suits relay driver boards, LED matrix control, and PLC output modules that require deterministic latch hold while the CPU services other tasks. Operating on supplies between 2 V and 6 V, it interfaces directly with both 3.3 V and 5 V logic families in mixed-voltage industrial control panels.

Frequently Asked Questions
How many output lines can CD74HC259E control, and what is the maximum sink current per output?
The CD74HC259E provides 8 independently addressable latched output lines, each capable of sinking up to 5.2 mA. This is sufficient to directly drive standard LEDs through a 270 Ω current-limiting resistor from a 5 V rail, or to toggle opto-coupler inputs in PLC relay interface boards without external buffer transistors.
For a 3.3 V microcontroller expanding to 8 relay control signals, how does CD74HC259E reduce the required MCU pin count?
Instead of requiring 8 dedicated GPIO pins, CD74HC259E needs only 3 address pins and 1 data pin from the microcontroller—saving 4 MCU pins. The 3-bit address selects one of the 8 latch outputs, and the data pin sets its state; once written, the latch holds the output state independently, freeing the MCU bus for other tasks without continuous refresh.
At 50 pF load capacitance and a 5 V supply, what propagation delay can be expected from CD74HC259E outputs?
At 50 pF load and 5 V supply, the HC-family CD74HC259E typically exhibits propagation delays of 7 ns to 15 ns from address-decode to output change, consistent with standard HC CMOS timing. This is fast enough for relay board refresh rates well above 1 kHz and LED multiplexing frequencies above 500 Hz without visible flicker in display applications.
