SN74AC10D

Overview

The SN74AC10D is a Texas Instruments logic gate featuring three independent 3-input positive-NAND gates in a 14-pin SOIC package. It operates within a supply voltage range of 2V to 6V and supports input voltages up to 6V. The device achieves a maximum propagation delay of 6.5ns at 5V. Recommended operating conditions specify an industrial temperature range from -40°C to +85°C.

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 requiring termination to VCC or GND when unused

Applications

• Alarm/tamper detect circuit
• S-R latch implementation

Procurement Notes

Verify current production status directly with Texas Instruments, as the SN74AC10D may be obsolete. Confirm availability of alternative packages such as SN74AC10DR for surface-mount integration. Ensure compliance with RoHS standards and lead finish specifications before finalizing procurement plans.

Selection Notes

Select this component for designs requiring wide supply voltage flexibility between 2V and 6V. Verify that the 14-pin SOIC footprint aligns with PCB layout constraints. Consider thermal resistance characteristics if multiple devices are utilized in close proximity on the same board.

Part Context

This part belongs to the SNx4AC10 family of triple 3-input positive-NAND gates manufactured by Texas Instruments. The 'D' suffix specifically denotes the 14-lead Small Outline Integrated Circuit (SOIC) package variant designed for surface-mount technology applications.
