SN74AC10DBR

Overview

The SN74AC10DBR is a Texas Instruments SNx4AC10 Triple 3-Input Positive-NAND Gate in a 14-pin SSOP package. It operates on a supply voltage (VCC) of 2V to 6V and accepts input voltages up to 6V. The maximum propagation delay (tpd) is 6.5ns at 5V. Recommended operating conditions specify an operating free-air temperature range of -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 with high impedance characteristics

Applications

• Alarm/tamper detect circuit
• S-R latch

Procurement Notes

Verify the specific ordering suffix 'DBR' corresponds to the SSOP-14 package and tape-and-reel carrier format. Confirm that the RoHS status and lead finish match project requirements, as these attributes are defined by the manufacturer's packaging addendum for this specific part number.

Selection Notes

Select this component when a triple 3-input NAND gate is required within the AC logic family. Ensure the design accommodates the specified 2V to 6V supply range and that input signals transition quickly to prevent oscillations associated with standard CMOS inputs.

Part Context

This device belongs to the SNx4AC10 series from Texas Instruments. It is part of the broader SN74AC logic family, which provides high-speed CMOS performance. The DBR suffix specifically denotes the SSOP surface-mount package variant available in reel or cut-tape formats.

FAQ

How should unused inputs be handled?

Unused inputs must be terminated at VCC or GND. They can be directly terminated if completely unused, or connected via a pull-up/pull-down resistor if used intermittently.

What is the maximum capacitive load recommended?

The device can drive a load with a total capacitance less than or equal to 50pF while meeting all data sheet specifications.
