74LS595 8-bit serial-to-parallel Shift Register Tri-State
Package SOIC-16, PDIP-16 Series 74LS Status Active (11-Nov-2021)
74ls595 overview
The 74LS series of integrated circuits (ICs) was one of the most popular logic families of transistor-transistor logic (TTL) logic chips. 74LS series is a bipolar, low-power Schottky IC. 74LS595 contains an 8-bit serial-in, parallel-out shift register that feeds an 8-bit D-type storage register
