HEF4077B Quad 2-input EXCLUSIVE-NOR gate Rev. 6 14 March 2017 Product data sheet 1 General description The HEF4077B is a quad 2-input EXCLUSIVE-NOR gate. The outputs are fully buffered for the highest noise immunity and pattern insensitivity to output impedance. The HEF4077B operates over a recommended V power supply range of 3 V to 15 V DD referenced to V (usually ground). Unused inputs must be connected to V , V , or SS DD SS another input. 2 Features and benefits Fully static operation 5 V, 10 V, and 15 V parametric ratings Standardized symmetrical output characteristics Specified from -40 C to +85 C Complies with JEDEC standard JESD 13-B 3 Ordering information Table 1.
