SN74HCS137DR TI Decoder/Demultiplexer | 16-SOIC | 1-of-8, 2V to 6V

Product Overview

The SN74HCS137DR is a high-performance 1-of-8 decoder/demultiplexer from Texas Instruments, featuring Schmitt-trigger inputs for enhanced noise immunity. Housed in a compact 16-SOIC package, this device operates over a wide voltage range of 2V to 6V, making it suitable for various logic-level applications. It is designed to decode three binary weighted address inputs (A0, A1, A2) to eight mutually exclusive outputs (Y0–Y7), with an active-low enable input (G) and an active-high enable input (G2) for flexible control. The device incorporates a latch on the address inputs, allowing for demultiplexing applications.
