Dual 4:1 multiplexer in a standard DIP footprint
The SN74LS153N is a dual 4:1 multiplexer from Texas Instruments' 74LS TTL family, selecting one of four data inputs per section under common address lines. Housed in a 16-pin DIP (0.300" body width, 7.62mm row spacing), the through-hole package mates with standard DIP sockets or solders directly into plated-through holes on a 0.100" pitch grid. The 16-PDIP supplier package matches the common DIP-16 footprint — no special layout or thermal management required for this logic-level part.
