Overview
The SN74AC10NSR is a Texas Instruments logic gate featuring three independent 3-input positive-NAND gates. It operates within a supply voltage range of 2V to 6V and accepts input voltages up to 6V. The device provides a maximum propagation delay of 6.5ns at 5V. It utilizes balanced CMOS push-pull outputs and standard CMOS inputs, requiring unused inputs to be terminated at VCC or GND. The component is housed in a 14-pin SOP (NS) package.
Feature Summary
- Contains three independent 3-input NAND gates performing the Boolean function Y = A • B • C
- Features balanced CMOS push-pull outputs capable of sinking and sourcing similar currents
- Includes standard CMOS inputs with high impedance characteristics
Applications
- Alarm/tamper detect circuit
- S-R latch implementation
Procurement Notes
Verify the specific NS (SOP) package designation against the datasheet to ensure compatibility with surface-mount assembly processes. Confirm that the ordering suffix matches the required production status and lead finish specifications provided in the manufacturer's packaging addendum. Ensure all unused inputs are properly terminated during system design to prevent oscillations.
Selection Notes
Select this component for designs requiring triple 3-input NAND functionality within a wide 2V to 6V supply range. The balanced push-pull output structure supports fast edges into light loads, necessitating careful routing considerations to prevent ringing. Verify that the operating temperature range meets the environmental requirements of the target application.
Part Context
This part belongs to the SNx4AC10 family of Triple 3-Input Positive-NAND Gates manufactured by Texas Instruments. The AC series offers performance characteristics suitable for general-purpose digital logic applications. The NS suffix specifically denotes the 14-pin Small Outline Package variant within the broader product line.

FAQ
How should unused inputs on the SN74AC10NSR be handled?
Unused inputs must be terminated at either VCC or ground. They can be directly terminated if completely unused, or connected via a pull-up or pull-down resistor if used intermittently.
What is the recommended bypass capacitor placement for this device?
A decoupling capacitor should be placed physically close to the device and electrically close to both the VCC and GND pins to prevent power disturbances.
