Toshiba Adds Hot-Swap General-Purpose Series to Family of Low-Voltage CMOS Logic ICs

IRVINE, Calif., Nov. 2, 2011 /PRNewswire/ -- 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 the TC74LCXZA 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.

Features of the TC74LCXZ and TC74LCXZA include:

• Hot-swap support: This function enables hot-swap applications when the main system is turned on.
• Lineup of the industry's first hot-swap 2.5V CMOS logic ICs: The TC74LCXZA Series is a 2.5V CMOS logic IC. This series is suitable as a replacement of 2.5V BiCMOS logic ICs.
• Achieves a reduction in consumption current. The TC74LCXZ Series: +40 microamperes (max.) at V(CC) = 2.7V to 3.6V (V(IN) = V(CC) or GND). The TC74LCXZA Series: +40 microamperes (max.) at V(CC) = 2.3V to 2.7V (V(IN) = V(CC) or GND).
• Interface between different power supplies can be realized with the tolerant function in both the input and output sections.
• TSSOP20 and US20 packages are available in this lineup. Footprint can be reduced by 50 percent with the US20 package compared to the TSSOP20 package.
• All inputs are equipped with protection circuits against static discharge.

Availability

The Toshiba TC74LCXZ and TC74LCXZA are available now.
