CD40117-Programmable dual 4-bit terminator
Series CD4000 (CMOS)
CD40117 overview
CD40117 belongs to the 4000 Series CMOS Logic Family of Integrated Circuits (IC's) constructed with N- and P-channel enhancement mode transistors. CD40117 has a Programmable dual 4-bit terminator
CD40117 has a supply voltage range of 5V to 20V, which is much higher than any contemporary logic family. It has buffered output which improves transfer characteristics by providing very high gain. All inputs are protected against static discharge with diodes to VDD and VSS.

CD40117 features
- One standard "8" output will drive eight terminator circuits.
- Will terminate a CMOS data bus with up to 40 B-series inputs or 3-state
- outputs connected at VDD of 5 V.
- Input terminals protected by standard "B" series ESD protection network.
- Preserves final logic state.
- Output after switching is closer to VDD or Vss ráll than with a resistor.
- Requires only one solder connection.
- Open circuited terminator not used will not affect performance.
- Can be connected to any CMOS i/O line.
- Draws current only when logic state is changing.
- Can be preset.
