Output drive capability is 6mA source and 6mA sink, typical for HCT-series logic at 5V. The 16-SOIC package (body width 3.90mm, pitch 1.27mm) is a standard JEDEC outline — the footprint matches any SOIC-16 land pattern and reflow profile common to 74HCT logic. No exposed pad or thermal slug; the part is convection-cooled through the leads and board copper. The tube packaging suits automated pick-and-place but also bench prototyping.","metaTitle":"SN74HCT157D Texas Instruments 74HCT Multiplexer, 4 x 2:1","metaDescription":"Texas Instruments SN74HCT157D 4 x 2:1 multiplexer, 74HCT logic family, 4.5V-5.5V supply, -40°C to 85°C, 16-SOIC.
