CD74HC137E TI Decoder/Demultiplexer | 16-PDIP | 3-to-8 Line, High-Speed CMOS

Product Overview

The CD74HC137E from Texas Instruments is a high-speed CMOS 3-to-8 line decoder/demultiplexer with latched inputs. It is designed for memory decoding and data routing applications in digital systems. The device features three address inputs (A0, A1, A2), three enable inputs (E1, E2, E3), and eight active-low outputs (Y0-Y7). The latched address inputs allow for stable decoding during address transitions. Operating from a 2V to 6V supply, it is compatible with TTL logic levels and offers low power consumption.
