CD74HCT137M96 TI Decoder/Demux | 16-SOIC | 3-to-8, Latched, High-Speed

Product Overview

The CD74HCT137M96 from Texas Instruments is a high-speed CMOS 3-to-8 line decoder/demultiplexer with input latches. It is designed for memory decoding and data routing applications where low power consumption and high noise immunity are required. The device features three address inputs (A0, A1, A2), three enable inputs (E1, E2, E3), and eight active-low outputs (Y0–Y7). The latches store the address inputs when the latch enable (LE) is low, allowing the outputs to remain stable even if the address lines change. The CD74HCT137M96 is fabricated using silicon gate technology, providing the speed of LSTTL with the low power consumption of CMOS. It operates over a wide supply voltage range of 4.5V to 5.5V and is fully compatible with TTL logic levels.
