HEF4000BP Dual 3-In NOR Gate Plus Inverter IC PDIP-14
The HEF4000BP Dual 3-In NOR Gate Plus Inverter IC PDIP-14 is a CMOS logic device that integrates two buffered 3-input NOR gates and a single inverter in a PDIP-14 through-hole package, offering low dynamic power dissipation, high input impedance and robust output buffering for use in wide-voltage digital and analogue timing applications.
Features
- Two independent 3-input NOR gates plus one inverter in a single PDIP-14 package for compact logic implementation.
- Fully buffered outputs for high noise immunity and consistent output impedance.
- CMOS inputs with very high input impedance and low quiescent current for battery-friendly designs.
- AC characteristics specified at VDD = 5V, 10V and 15V for flexible supply options.
- Typical propagation-delay expressions provided for load capacitance based timing estimates.
- Suitable for use as logic gates or as an analogue inverter stage in timing/amplifier circuits.
- Available in plastic PDIP (HEF4000BP) for easy prototyping.
