Description:
The 74HC138 3 To 8 Line Decoder DIP 16 IC – Pack of 5 is a high-speed CMOS logic device used to convert 3 binary input signals into 8 mutually exclusive outputs. Each output is active low, making this IC ideal for address decoding, data routing, and demultiplexing in digital systems. It features three enable inputs (two active-low and one active-high) to allow flexible cascading and expansion across multiple devices.
Operating from a supply voltage range of 2V to 6V and fully compatible with TTL logic levels, the 74HC138 offers fast switching performance with typical propagation delays under 20 ns. Housed in a DIP-16 through-hole package, this IC is suitable for breadboards and PCB prototyping. This 5-pack provides a reliable and versatile solution for applications involving memory addressing, I/O selection, or microcontroller expansion.
