NC7SZD384

TinyLogic UHS 1-Bit Low Power Bus Switch

with Level Shifting

General Description

Features

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.

■ Space saving SOT23 or SC70 5-lead package

■ Ultra small MicroPak leadless package

■ 5Ω switch connection between two ports

■ Designed to be used in level-shifting applications

■ Minimal propagation delay through the switch

■ Low I_CC

■ 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: All typical values are at V_CC= 5.0V, T_A= 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 (V_IN= 3.4V, control input only). A and B pins do not contribute to I_CC.
