HLF 74LS266 Quadruple 2-Input Exclusive-NOR Gates with Open-Collector Outputs – DIP16 | High-Speed TTL Logic | 4.75V–5.25V, 0°C to +70°C | Through-Hole Package

HLF

The HLF 74LS266 is a quadruple 2-input Exclusive-NOR (XNOR) gate featuring open-collector outputs, designed using Low-Power Schottky TTL (LS) technology. Each gate provides high-speed logic operation with excellent noise immunity, making it ideal for digital comparison, parity checking, and combinational logic applications.

The open-collector outputs allow wired-AND connections and interface with higher voltage loads through external pull-up resistors. The DIP16 through-hole package ensures easy integration into breadboards, prototyping, and industrial PCBs.
