SN74HCU04DT

Inverter Gates Overview

The SN74HCU04DT is an obsolete hex inverter from the Texas Instruments SN74HCU04 series, housed in a 14-pin SOIC package. It operates within a supply voltage range of 2 V to 6 V and supports an operating temperature range of -40°C to +85°C. The device features unbuffered outputs capable of driving up to 10 LSTTL loads, with typical output drive currents of ±4 mA at 5 V. Electrical characteristics include a maximum input current of 1 µA and a maximum quiescent current of 20 µA. Propagation delay typically ranges from 7 ns to 20 ns depending on the supply voltage.

Inverter Gates Procurement Notes

Verify component obsolescence status before procurement as this specific part number is marked obsolete by the manufacturer. Confirm availability through authorized distributors or secondary markets. Ensure that any replacement components maintain identical pinout configurations and electrical specifications to guarantee compatibility with existing circuit designs without requiring board modifications.

Inverter Gates Selection Notes

Select this component for applications requiring standard hex inverter functionality within the HC logic family. Consider alternative active packages such as SN74HCU04DR if tape-and-reel packaging is preferred over cut tape. Evaluate power consumption requirements against the specified 20-µA maximum ICC rating. Verify that the SOIC-14 package dimensions align with the target PCB footprint constraints.

Inverter Gates Part Context

This device belongs to the SN74HCU04 family of high-speed CMOS logic circuits manufactured by Texas Instruments. The 'HCU' designation indicates unbuffered outputs, distinguishing it from buffered variants like the SN74HC04. The 'DT' suffix specifies the SOIC-14 surface-mount package configuration. This family provides general-purpose digital logic functions suitable for various consumer and industrial electronic applications.
