The 74LS166 is a low-power Schottky TTL IC containing an 8-bit shift register with synchronous parallel load. It acts as a parallel-in, serial-out (PISO) register. Eight parallel data inputs are loaded synchronously with the clock when the shift/load input is low, after which data shifts out synchronously on the QH serial output. It features a serial input for cascading and a clock-inhibit input. It is commonly used to expand inputs on microcontrollers. It runs from a 5 V supply. It comes in a 16-pin plastic DIP.
Condition: mixed surplus lot, untested. The bag may contain used (pulled) ICs of the same type from different manufacturers, so marking and date code vary. The photo shows one chip from this lot (Hitachi HD74LS166AP 4M4 T); only the background was cleaned to white, preserving the marking and leads.
Minimum order: 1 pc.
