Procurement Notes

Verify that the specific part number matches the required package style and lead configuration before procurement. Confirm compliance with RoHS directives and environmental regulations relevant to your region. Ensure the supplier provides valid traceability documentation. Check for any recent Product Change Notifications regarding manufacturing updates or pinout modifications. Validate that the component meets the specific electrical requirements of your target application circuit.

Selection Notes

Select this component when high-speed switching capabilities are required alongside robust noise immunity. The ACT series offers superior performance compared to standard TTL or older CMOS families. Consider the wide operating temperature range if the application involves extreme thermal conditions. Verify that the power supply voltage strictly adheres to the specified 4.5 V to 5.5 V limits to ensure optimal device longevity and signal integrity.

Part Context

This component belongs to the Texas Instruments 74ACT family, which bridges the speed of bipolar logic with the low power consumption of CMOS technology. The '74' designation indicates a standard logic function, while 'ACT' specifies the advanced CMOS process. The 'ME4' suffix denotes the SOIC surface-mount package and RoHS-compliant material composition. This family is widely used in complex digital systems requiring fast propagation delays.
