SN74AHCT04BQAR

Overview

The SN74AHCT04BQAR is a hex inverter from the Texas Instruments SNx4AHCT04 family, housed in a 14-pin WQFN (BQA) package. It operates on a supply voltage of 4.5 V to 5.5 V and supports an operating temperature range of -40°C to +125°C. The device features TTL-compatible inputs with high-level input voltage thresholds of 2 V and low-level thresholds of 0.8 V. It provides balanced output drive currents of ±8 mA and includes latch-up performance exceeding 250 mA per JESD 17.

Feature Summary

• TTL-voltage compatible inputs allow up-conversion from 3.3 V logic levels to 5 V systems
• Slow edge rates minimize output ringing and overshoot for signal integrity
• High ESD protection with latch-up performance exceeding 250 mA per JESD 17

Applications

• Servers
• Network switches
• Telecom infrastructures
• Tests and measurements

Procurement Notes

Verify the specific BQA suffix indicates the WQFN-14 package configuration. Confirm RoHS compliance and lead finish details against the latest Package Option Addendum. Ensure design reviews account for the specified thermal resistance values associated with the WQFN footprint during PCB layout.

Selection Notes

Select this component when TTL compatibility is required at 5 V operation. The slow edge rate feature makes it suitable for applications where minimizing output ringing is critical. Verify that the 14-pin WQFN package dimensions fit the available board space and thermal requirements.

Part Context

This part belongs to the SNx4AHCT04 series of hex inverters manufactured by Texas Instruments. The 'SN' prefix denotes commercial grade devices, while 'AHCT' specifies the advanced high-speed CMOS technology with TTL-compatible inputs. The 'BQA' suffix identifies the specific 14-pin WQFN package variant.

Replacement Considerations

Direct pin-to-pin replacements within the same package include other SN74AHCT04 variants such as SN74AHCT04DR or SN74AHCT04RGYR. Verify package type and electrical specifications before substitution.
