CD40117B,pdf(TYPES)

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".
