NC7SZ384
TinyLogic UHS 1-Bit Low Power Bus Switch
General Description
Features
The NC7SZ384 provides 1-bit of ultra high-speed CMOS
TTL-compatible bus switch. The low On Resistance of the
switch allows inputs to be connected to outputs with mini-
mal 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.
■ Space saving SOT23 or SC70 5-lead package
■ Ultra small MicroPak leadless package
■ 5Ω switch connection between two ports
■ Minimal propagation delay through the switch
■ Low ICC
■ Zero bounce in flow-through mode
■ 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 4: 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 5: Per TTL driven input (VIN = 3.4V, control input only). A and B pins do not contribute to ICC

Note 6: All typical values are VCC = 5.0V, TA = 25°C.
Note 7: 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).
Note 8: TA = 25°C, f = 1 MHz.
