SN74HCS251QDRQ1 TI Multiplexer | 16-SOIC | 8-Ch, 2V-6V

Product Overview

The SN74HCS251QDRQ1 is a high-speed CMOS 8-input multiplexer from Texas Instruments, designed for automotive applications. It features Schmitt-trigger inputs, low power consumption, and operates over a wide voltage range of 2V to 6V. The device selects one of eight data inputs based on the state of three select lines (S0, S1, S2) and provides a complementary output (Y and Y̅). It is qualified to AEC-Q100 standards, making it suitable for harsh automotive environments.
