SN74HC151PW Description

The SN74HC151PW from Texas Instruments is a high-performance 1 x 8:1 multiplexer (MUX) integrated circuit designed for digital signal routing applications. Housed in a 16-pin TSSOP (Thin Shrink Small Outline Package), this device operates over a wide voltage range of 2V to 6V, making it compatible with both 3.3V and 5V logic systems. It belongs to the 74HC series, known for its low power consumption and high-speed CMOS technology. The IC features a single 8-channel input and delivers 7.8mA output current (both high and low), ensuring robust signal integrity. With REACH and RoHS3 compliance, it meets stringent environmental standards, while its Moisture Sensitivity Level (MSL) 1 rating ensures reliability in various handling conditions.
