74HCT04DR2G

Overview

The onsemi 74HCT04DR2G is a high-performance silicon-gate CMOS hex inverter featuring LSTTL-compatible inputs. It operates within a DC supply voltage range of 4.5 to 5.5 V and supports an operating temperature range from -55°C to +125°C. The device provides an output drive capability of 10 LSTTL loads, with maximum propagation delays of 15 ns at -55 to 25°C and 26 ns at up to 125°C under a 50 pF load. It includes ESD protection exceeding 2000 V (HBM) and complies with JEDEC Standard No. 7A.

Feature Summary

• Provides direct interfacing between TTL or NMOS outputs and High-Speed CMOS inputs via LSTTL-compatible input levels.
• Features low input current consumption of 1.0 µA and robust ESD performance meeting HBM > 2000 V standards.
• Designed for level conversion applications while maintaining identical pinout compatibility with LS04 devices.

Applications

• Level conversion for interfacing TTL or NMOS outputs to High-Speed CMOS inputs
• General-purpose logic inversion in digital circuits
• Signal buffering where LSTTL drive capability is required

Procurement Notes

Verify the specific package suffix 'D' corresponds to the SOIC-14 configuration as documented in the ordering information table. Confirm that the 'R2G' suffix indicates tape and reel packaging with a quantity of 2500 units. Ensure compliance requirements such as Pb-Free status are validated against the latest manufacturer documentation before finalizing procurement specifications.

Selection Notes

Select this component when LSTTL-compatible input thresholds are necessary for interfacing with legacy TTL or NMOS logic families. The wide operating temperature range of -55°C to +125°C makes it suitable for industrial environments. Consider the SOIC-14 surface-mount package for space-constrained PCB layouts requiring standard 14-pin footprint compatibility.

Part Context

This part belongs to the 74HCT04 series of hex inverters manufactured by onsemi. It utilizes high-performance silicon-gate CMOS technology to achieve low power consumption while maintaining fast switching speeds. The device is functionally equivalent to other industry-standard hex inverters but offers specific drive capabilities tailored for LSTTL loads.

Replacement Considerations

The datasheet notes that the HCT04A is identical in pinout to the LS04. Verify cross-compatibility with other manufacturers' 74HCT04 variants if system-level pinout matching is critical.
