What are the key features of CD74HC238E?
- 3-line to 8-line decoding with active-high outputs directly drives LEDs, relays, or memory select lines
- 4 mA output sink/source current supports moderate load driving without external buffers in most logic designs
- HC CMOS family ensures compatibility with 2 V to 6 V systems and TTL-level inputs for mixed-logic integration
What is CD74HC238E used for?
The CD74HC238E is commonly used in address decoding for memory expansion, port selection, and peripheral enabling in microprocessor-based systems. Its 3-to-8 line decoder function with active-high outputs suits applications such as driving 8 individual enable lines from a 3-bit bus, reducing wire count and I/O pin usage. Industrial and consumer electronics designers also use it in multiplexed display and keypad scanning circuits where compact 16-pin DIP packaging aids prototyping and low-volume production.

Frequently Asked Questions
What output configuration does the CD74HC238E use, and how much current can each output sink?
The CD74HC238E uses active-high decoded outputs, meaning only the selected output goes high while all others remain low. Each output can sink up to 4 mA, sufficient to drive standard LEDs or logic inputs directly without external current amplifiers, simplifying circuit design in address decoders and peripheral enable applications.
How does the CD74HC238E differ from the CD74HC138E in a memory address decoding circuit?
The CD74HC238E has active-high outputs—only the selected output asserts high—while the CD74HC138E has active-low outputs where the selected line goes low. In memory decoding, active-low chip-select inputs on SRAM or ROM devices are better matched to the CD74HC138E, whereas devices with active-high enables, such as certain latches or display drivers, pair naturally with the CD74HC238E. Both operate with 50 pF load and 4 mA drive at up to 6 V supply.
For a low-volume PCB prototype, what makes the CD74HC238E DIP-16 package preferable over an SOIC variant?
The CD74HC238E in a 16-pin DIP package can be inserted directly into a breadboard or IC socket, enabling fast swapping during debugging and eliminating the need for hot-air rework tools. For prototyping runs of fewer than 50 boards, the through-hole DIP-16 form factor reduces assembly time and tooling cost compared to soldering a 16-pin SOIC variant by hand under magnification.
