Logic Functions have DQFN form factor.
June 11, 2004 - Quad-, 6- and 8-bit LCX and VCX series low-voltage logic functions reduce noise and crosstalk between I/O terminals. Chips have exposed die attach paddle underneath and visible solder joints. Products include 2.5–3.3 V bi-directional octal transceiver; 2.5–3.3 V octal buffer line driver; 2.5–3.3 V decoder/demultiplexer; 1.2–3.3 V quad dual-input and gate; and 1.4–3.3 V bi-directional octal transceiver.

Fairchild Introduces Low-Voltage Logic Functions in Ultra-Compact DQFN Packaging -- Up to 75% Smaller than TSSOP
Industry's smallest package facilitates added functionality in new 2.5G and 3G cell phones
South Portland, Maine-June 9, 2004-Fairchild Semiconductor (NYSE: FCS), announces the immediate availability of several 4-, 6- and 8-bit LCX and VCX series low-voltage logic functions in the DQFN (Depopulated very thin Quad Flat-pack No leads) form factor. DQFN, the industry's smallest package for quad, hex and octal logic functions, represents a 75% space savings over traditional TSSOP (Thin Shrink Small Outline Package) devices. DQFN is the optimal solution for facilitating feature additions in next-generation cell phones, digital cameras, camera-phones and other ultra-portable battery-powered applications.
DQFN provides a number of important design benefits. Noise and crosstalk between I/O terminals is reduced compared to leaded packages due to the lower capacitance and inductance of DQFN. Chips in DQFN also run cooler than in leaded packages due to the exposed die attach paddle underneath. DQFN has visible solder joints which facilitate easy inspection. DQFN packaged logic is second-sourced for assured supply.
"DQFN's smaller form factor enables more compact designs," says Ken Murphy, Fairchild's marketing manager for Logic products. "For example, the 74LCX138BQX decoder/demultiplexer in DQFN can expand the available control signals from the microprocessor to the LCD display and LED drivers for MP3 players, while conserving space."
Currently available LCX and VCX series devices in DQFN include:
• 74LCX245BQX: 2.5V to 3.3V bi-directional octal transceiver with 5V tolerant inputs and outputs;
• 74LCX244BQX: 2.5V to 3.3V octal buffer line driver with 5V tolerant I/O;
• 74LCX138BQX: 2.5V to 3.3V (1-of-8) decoder/demultiplexer with 5V tolerant I/O;
• 74VCX08BQX: 1.2V to 3.3V Quad dual-input AND gate with 3.6V tolerant inputs; and
• 74VCX245BQX: 1.4V to 3.3V bi-directional octal transceiver with 3.6V tolerant inputs.
Fairchild's LCX and VCX logic functions are fabricated with an advanced CMOS technology to achieve high-speed operation while maintaining low power dissipation. All models implement the company's patented noise/EMI reduction circuitry and support live insertion/withdrawal. Electrostatic discharge (ESD) performance is exceptional, with machine and human body models rated at greater than 200V and 2000V, respectively. All part numbers are available in 3000-piece tape reel formats compatible with high-speed manufacturing processes.
The introduction of these low-voltage logic products in DQFN further expands Fairchild's innovative package offering that includes FLMP, MicroPak™ and BGA form factors.
These lead-free (Pb-free) products meet or exceed the requirements of the joint IPC/JEDEC standard J-STD-020B and are compliant with the European Union requirements that will take effect in 2005.
