• Manufacturer Part Number: hef4000b
• Description: Dual 3-input Nor Gate And Inverter
• Manufacturer: NXP Semiconductors

Philips Semiconductors
DESCRIPTION
The HEF4000B provides the positive dual 3-input NOR
function. A single stage inverting function with standard
output performance is also accomplished. The outputs are
fully buffered for highest noise immunity and pattern
insensitivity of output impedance.
