tPD= 50ns (TYP.)at VDD= 10VCL= 50pF BUFFERED INPUTS AND OUTPUTS STANDARDIZED SYMMETRICAL OUTPUT
CHARACTERISTICS QUIESCENT CURRENT SPECIFIED UP TO
20V 5V, 10V AND 15V PARAMETRIC RATINGS INPUT LEAKAGE CURRENT= 100nA (MAX)AT VDD =18VTA= 25°C 100% TESTED FOR QUIESCENT CURRENT
DESCRIPTIONThe HCF4001Bisa monolithic integrated circuit
fabricated in Metal Oxide Semiconductor
technology availablein DIP and SOP packages.
The HCF4001B QUAD 2-INPUT NOR GATE
provides the system designer with direct
implementation of the NOR function and
supplement the existing familyof CMOS gates.All
inputs and outputs are buffered.
