What are the key features of SN74HC238N?
- 3-to-8 line active-high decoding enabling direct chip-select generation without external inverters
- Wide 2 V to 6 V supply range compatible with 3.3 V and 5 V logic systems in the HC family
- Three enable inputs allowing cascading of multiple SN74HC238N devices to expand decoding up to 4-to-16 lines
What is SN74HC238N used for?
The SN74HC238N is used in microprocessor memory address decoders, I/O port expanders, and bus demultiplexers for 8-bit and 16-bit embedded systems. Its three enable inputs allow designers to cascade two devices to decode 4 address bits into 16 chip-select lines, scaling address space in 6802 or Z80 type systems. Hobbyist and prototyping boards also rely on its 16-pin DIP footprint for easy breadboard and through-hole assembly without surface-mount equipment.

Frequently Asked Questions
Which designs benefit from SN74HC238N's 50 pF rating?
SN74HC238N fits filtering and RF matching and related production circuits where designers need surface mount capacitor behavior with 50 pF, 2 V, -40°C to 85°C and 16 pins. The Dual-In-Line Packages format and 16 pins configuration support compact automated assembly.
How should engineers review the Dual-In-Line Packages footprint before approving SN74HC238N?
Check the recommended land pattern, solder process, and clearance for Dual-In-Line Packages before release. Its 16 pins configuration and -40°C to 85°C rating make it practical for dense SMT boards.
What procurement checks matter before sourcing SN74HC238N for production builds?
Confirm Texas Instruments traceability, lifecycle status, and lot consistency before release. The buyer should match the quoted part to 50 pF, 2 V, -40°C to 85°C and 16 pins and verify 16 pins packaging requirements.
