NC7SZD384
TinyLogicUHS 1-Bit Low Power Bus Switch
with Level Shifting
General Description
The NC7SZD384 provides 1-bit of high-speed CMOS TTL-
compatible bus switch. The low on resistance of the switch
allows inputs to be connected to outputs with minimal prop-
agation 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
s Space saving SOT23 or SC70 5-lead package
s Ultra small MicroPakleadless package
s 5switch connection between two ports
s Designed to be used in level-shifting applications
s Minimal propagation delay through the switch
s Low ICC
s Zero bounce in flow-through mode
s Control inputs compatible with TTL level

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 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
