Revised April 2003 NC7WBD3306 NC7WBD3306 TinyLogic UHS 2-Bit Low Power Bus Switch with Level Shifting General Description Features The NC7WBD3306 NC7WBD3306 is a 2-bit ultra high-speed CMOS FET bus switch with enhanced level shifting circuitry and with TTL-compatible active LOW control inputs. The low On Resistance of the switch allows inputs to be connected to outputs with minimal propagation delay and without generating additional ground bounce noise. The device is organized as a 2-bit switch with independent bus enable (OE) controls. When OE is LOW, the switch is ON and Port A is connected to Port B. When OE is HIGH, the switch is OPEN and a high-impedance state exists between the two ports. Reduced voltage drive to the gate of the FET switch permits nominal level shifting of 5V to 3V through the switch. Control inputs tolerate voltages up to 5.5V independent of VCC. s Space saving US8 surface mount package s MicroPak leadless package s Typical 3 switch resistance at 5.0V VCC , VIN = 0V s Level shift facilitates 5V to 3.3V interfacing s Minimal propagation delay through the switch s Power down high impedance input/output s Zero bounce in flow through mode s TTL compatible active LOW control inputs s Control inputs are overvoltage tolerant Ordering Code: Product Order Number Package Code Package Description Supplied As Number Top Mark NC7WBD3306K8X NC7WBD3306K8X MAB08A MAB08A WB6D NC7WBD3306L8X NC7WBD3306L8X MAC08A MAC08A (Preliminary) P7 8-Lead US8, JEDEC MO-187 MO-187, Variation CA 3.1mm Wide 3k Units on Tape and Reel 8-Lead MicroPak, 1.6 mm Wide 5k Units on Tape and Reel TinyLogic is a registered trademark of Fairchild Semiconductor Corporation.

The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings. The "Recommended Operating Conditions" table will define the conditions for actual device operation. 250 mW Note 2: The input and output negative voltage ratings may be exceeded if the input and output diode current ratings are observed.
