Revised November 2000 NC7SZD384 TinyLogic UHS 1-Bit Low Power Bus Switch with Level Shifting General Description Features The NC7SZD384 provides 1-bit of high-speed CMOS TTLcompatible bus switch. 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 1-bit switch with a bus enable (OE) signal. 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 3.3V through the switch. ■ Space saving SOT23 or SC70 5-lead package. ■ 5Ω switch connection between two ports. ■ Designed to be used in level-shifting applications. ■ Minimal propagation delay through the switch. ■ Low ICC. ■ Zero bounce in flow-through mode. ■ Control inputs compatible with TTL level.

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. Note 2: The input and output negative voltage ratings may be exceeded if the input and output diode current ratings are observed. Note 3: Unused inputs must be held HIGH or LOW. They may not float.
