SN74HC151ANSR-P

Overview

The SN74HC151ANSR-P is an 8-line to 1-line data selector/multiplexer from Texas Instruments' HC logic family. It features a wide operating voltage range of 2 V to 6 V and operates within a temperature range of -40°C to +85°C. The device provides complete binary decoding to select one of eight data sources, utilizing three address inputs. It includes a strobe (G) input that forces the standard output (Y) low and the inverted output (W) high when active. Packaged in a 16-SOIC surface-mount format, it offers low power consumption with a maximum static current of 80 µA.

FAQ

How does the strobe input affect the outputs?

When the strobe (G) input is at a high logic level, it forces the standard output (Y) to a low state and the inverted output (W) to a high state, regardless of the address inputs.

What is the maximum static current consumption?

The device has a maximum static supply current (ICC) of 80 µA, contributing to its low power consumption profile.
