HEF4002B

HEF4002B Dual 4-input NOR gate Rev. 4 — 17 October 2016 Product data sheet 1. General description The HEF4002B is a dual 4-input NOR gate. The outputs are fully buffered for highest noise immunity and pattern insensitivity to output impedance variations. 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. 2. Features and benefits  Fully static operation  5 V, 10 V, and 15 V parametric ratings  Standardized symmetrical output characteristics  Inputs and outputs are protected against electrostatic effects  Specified from 40 C to +85 C  Complies with JEDEC standard JESD 13-B 3. Ordering information Table 1. Ordering information All types operate from 40 C to +85 C. Type number Package Name HEF4002BT SO14 Description plastic small outline package; 14 leads; body width 3.9 mm Version SOT108-1 4. Functional diagram  $  %  &  '  $  %  &  ' <  <  DDD Fig 1.
