Series Includes Industry's First Hot-Swap 2.5V CMOS Logic IC
IRVINE Calif., — Toshiba America Electronic Components, Inc., (TAEC)*, a committed leader that collaborates with technology companies to create breakthrough designs, has announced the addition of the TC74LCXZ and TC74LCXZA to its family of low-voltage CMOS logic ICs. The new ICs from Toshiba feature a built-in power-up/power-down HZ (high-impedance) function and can maintain output at high impedance when power supply voltages are in the range of 0 to 1.5V (TC74LCXZ Series) and 0 to 1.2V (TC74LCXZA Series). This function enables hot-swap applications when the main system is turned on. Both the 74LCXZ and 74LCXZA come in 3-State inverted and non-inverted buffer.
Hot-swap ICs manage inrush current during live insertion of cards in order to prevent system failures. Hot-swap applications include factory automation and network equipment.
The TC74LCXZ and TC74LCXZA Series can be used for 3.3V and 2.5V systems respectively, and theTC74LCXZA Series, in particular, is one of the industry's first hot-swap 2.5V CMOS logic ICs. In addition, this new series of ICs can achieve a reduction in consumption current for BiCMOS logic ICs.
