Nexperia HEF4011BT,652, Quad 2-Input NAND Logic Gate, 14-Pin SOIC

The HEF4011B is a quad 2-input NAND gate. The outputs are fully buffered for the highest noise immunity and pattern insensitivity to output impedance. It operates over a recommended VDD power supply range of 3 V to 15 V referenced to VSS(usually ground). Unused inputs must be connected to VDD, VSS, or another input.
