Each of the four sections selects one of two data inputs and routes it to the output, controlled by a common select line. ## Pinout and board fit for the 16-DIP package Housed in a 16-DIP (0.300\" row spacing, 7.62 mm body width), the SN74HC257N is a through-hole part — it plugs into a standard 0.100\" pitch socket or solders directly into plated-through holes on a two-layer board. The 16-PDIP supplier package code is the same footprint. Output drive is rated 7.8 mA source and 7.8 mA sink at the supply rails — enough to drive a few HC-family inputs or a low-power LED, but not a bus or a relay coil without a buffer.","metaTitle":"SN74HC257N Texas Instruments 74HC Multiplexer, 4 x 2:1","metaDescription":"SN74HC257N 74HC quad 2:1 multiplexer, 2V-6V supply, -40°C to 85°C, 16-DIP.
