CD40117B 可编程双路 4 位终端 (20V 额定)
CD40117B is a dual 4-bit terminator that can be programmed by means of STROBE and DATA control bits to function as pull-up or pull-down resistors. The CD40117B can also be programmed to function as latches to terminate any open or unused CMOS logic when used with 3-state logic or during a power-down condition. Considerable savings in power and board space can be realized when this device is used to replace pull-up or pull-down resistors. When the STROBE is in the logic "1" state, the terminator functions as a pull-up resistor if the DATA input is a logic "1" or as a pull down resistor if the DATA input is a logic "0".
When the STROBE is in the logic "0" state, the terminator performs the latch functions,

CD40117B 特性
- One standard "B" output will drive eight terminator circuits.
- Will terminate a CMOS data bus with up to 40 B-series inputs inputs or 3-state outputs connected at VDD of 5 V.
- Input terminal protected by standard "B" series ESD protection network.
- Preserves final logic state.
- Output after switching is closer to VDD or VSS rail 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.
- Applications
- Error state identification.
- Replaces pull-up or pull-down resistors
- Avoids floating inputs in modular systems
- Sharpens transistors (hysteresis)
- Anti-bounce circuit
