| INTEGRATED CIRCUITS DATA SHEET For a complete data sheet, please also download: * The IC04 LOCMOS HE4000B Logic Family Specifications HEF, HEC * The IC04 LOCMOS HE4000B Logic Package Outlines/Information HEF, HEC HEF4072B gates Dual 4-input OR gate Product specification File under Integrated Circuits, IC04 January 1995 Philips Semiconductors Product specification Dual 4-input OR gate DESCRIPTION The HEF4072B provides the positive dual 4-input OR function. The outputs are fully buffered for highest noise immunity and pattern insensitivity of output impedance. HEF4072B gates Fig.2 Pinning diagram. HEF4072BP(N): 14-lead DIL; plastic (SOT27-1) HEF4072BD(F): 14-lead DIL; ceramic (cerdip) (SOT73) HEF4072BT(D): 14-lead SO; plastic Fig.1 Functional diagram. (SOT108-1) ( ): Package Designator North America Fig.3 Logic diagram (one gate).
