SN74ACT10QPWRG4Q1

Overview

The SN74ACT10QPWRG4Q1 is an automotive-grade triple 3-input positive-NAND gate manufactured by Texas Instruments. It operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature from -40°C to +125°C. The device features TTL-compatible CMOS inputs and balanced push-pull outputs capable of sourcing and sinking up to 24mA. Maximum propagation delay is 9.5ns at 5V. It is available in a TSSOP-14 package.

Feature Summary

• Qualified for automotive applications with extended temperature support
• TTL-voltage compatible inputs for direct interfacing
• Balanced CMOS push-pull outputs for high drive capability

Applications

• Alarm and tamper detection circuits
• S-R latch configurations

Procurement Notes

Verify the specific ordering suffix matches the required package type, as variants exist for both TSSOP and WQFN packages. Confirm that the component meets AEC-Q100 standards for your specific automotive environment. Ensure input signals transition rapidly to prevent oscillation and excessive power consumption due to the TTL-compatible nature of the CMOS inputs.

Selection Notes

Select this component when designing systems requiring three independent NAND gates with high-speed performance and robust automotive qualification. It is suitable for interfaces needing TTL compatibility while maintaining CMOS low static power characteristics. Consider the 24mA output drive strength for driving moderate loads directly without additional buffering stages.

Part Context

This part belongs to the SN74ACT series of logic ICs, specifically designed for automotive environments. It provides a reliable solution for implementing complex Boolean logic functions in vehicle electronics where high noise immunity and wide operating voltage ranges are critical requirements.

FAQ

How should unused inputs be handled?

Unused inputs must be terminated to either VCC or ground. They can be connected directly or via a pull-up/pull-down resistor, typically 10kΩ, to ensure valid logic states.

What is the maximum capacitive load supported?

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