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,

Technology Family	CD4000

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
