NC7SZD384 TinyLogic UHS 1-Bit Low Power Bus Switch with Level Shifting
June 1997 Revised May 2003
NC7SZD384 TinyLogic UHS 1-Bit Low Power Bus Switch with Level Shifting
General Description
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.
Features

Note 1: The "Absolute Maximum Ratings" are those values beyond which the safety of the device cannot be guaranteed. 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.

Note 4: All typical values are at VCC = 5.0V, TA= 25°C. Note 5: Measured by the voltage drop between A and B pins at the indicated current through the switch. On Resistance is determined by the lower of the voltages on the two (A or B) pins. Note 6: Per TTL driven input (VIN = 3.4V, control input only). A and B pins do not contribute to ICC.

Note 7: All typical values are VCC = 5.0V, TA = 25°C. Note 8: This parameter is guaranteed by design but is not tested. The bus switch contributes no propagation delay other than the RC delay of the typical On Resistance of the switch and the 50 pF load capacitance, when driven by an ideal voltage source (zero output impedance).
