Fairchild Semiconductor Expands CROSSVOLT LCX Family with New 74LCX06 and 74CX07 Devices
Fairchild Semiconductor (South Portland, ME) announced it has expanded the CROSSVOLT LCX low voltage logic family with the addition of the 74LCX06 and 74CX07. According to Fairchild, these devices are ideal for achieving maximum current drive without system or device damage.The devices feature 5V over-voltage tolerance on the inputs and output and provide a low voltage upgrade path for legacy DM7406 and DM7407 devices. When included on the Intel 810 (Whitney chipset) reference design for the Celeron processor, the 74LCX06 and 74LCX07 are used to drive LEDs from the IDE connector and the integrated controller hub as well as to drive power supply control signals and buffer power status signals in the voltage regulator module.The 74LCX06 is a low voltage hex inverter/buffer with open drain outputs, and the 74LCX07 is a low voltage hex buffer with open drain outputs. Both can be connected to other open drain outputs to implement active LOW wire AND or active HIGH wire OR functions. They both also feature patented noise/EMI reduction circuitry and edge rate control circuitry to reduce ground bounce and EMI.The devices, fabricated with an advanced CMOS technology, achieve high-speed operation (<4.0ns max.) while maintaining CMOS low power (10uA Icc). The 74LCX06 and 74LCX07 incorporate power down high impedance inputs and outputs as well as 2.0 to 3.6Vcc supply operation.Both devices are available in SOIC and TSSOP packages. In quantities of 1,000, the devices are priced at $0.19 each.
