CD74HC147M

Signal Switches, Multiplexers, Decoders Overview

The CD74HC147M is a high-speed CMOS logic component manufactured by Texas Instruments, functioning as a 10-line to 4-line priority encoder. It accepts ten active-low decimal inputs and provides four active-low binary-coded decimal (BCD) outputs. The device operates within a supply voltage range of 2 V to 6 V and supports an extended industrial temperature range from -55 °C to +125 °C. It is housed in a 16-pin Small Outline Integrated Circuit (SOIC) package with a width of approximately 3.91 mm.
