onsemi 74HC04DTR2G

Overview

74HC04DTR2G from onsemi is a high-performance silicon-gate CMOS hex inverter in 14-lead TSSOP package, operating from 2.0 V to 6.0 V, delivering 10 LSTTL load drive capability per output, with propagation delay as low as 13 ns at 6.0 V, and used for logic-level inversion in digital control, clock buffering, and signal conditioning circuits.

For engineers reviewing the 74HC04DTR2G datasheet, pinout, applications, or equivalent options, key selection considerations include supply voltage range (2.0–6.0 V), guaranteed output drive (±25 mA per pin), input compatibility with TTL/CMOS, thermal limits (–55°C to +125°C), and Pb-free TSSOP-14 packaging.

Technical Context

The 74HC04DTR2G implements six independent three-stage CMOS inverters in a single monolithic IC, each with rail-to-rail output swing and high noise immunity. Its inputs accept standard CMOS logic levels and-when pulled up-LSTTL-compatible signals.

It operates across industrial temperature (–55°C to +125°C) and supports dynamic performance up to 25 MHz typical at 5 V, with input capacitance ≤10 pF and power dissipation capacitance of 20 pF per inverter. No internal clamping diodes are present; unused inputs must be tied to VCC or GND.

FAQ

What is the maximum operating frequency supported by the 74HC04DTR2G?

The 74HC04DTR2G does not specify a hard maximum clock frequency, but its propagation delay (13 ns max at 6.0 V) and transition time (13 ns max) support reliable operation up to approximately 25 MHz in typical 50 pF load conditions. For sustained high-frequency use, ensure proper decoupling and minimize trace capacitance to maintain timing margins.

Can the 74HC04DTR2G operate at 3.3 V supply voltage?

Yes, the 74HC04DTR2G is fully specified for operation at 3.3 V (within its 2.0–6.0 V range). At 3.3 V, it delivers VOH ≥ 3.15 V and VOL ≤ 0.26 V under 4.0 mA load, ensuring solid noise margins and compatibility with 3.3 V CMOS and LVTTL interfaces.

Is the 74HC04DTR2G pin-compatible with the 74LS04?

Yes-the 74HC04DTR2G has identical pinout to the 74LS04 and MC14069, as confirmed in the official datasheet. However, due to CMOS input structure, it requires pull-up resistors for LSTTL input compatibility and cannot directly replace LS04 in open-collector configurations without external biasing.

Does the 74HC04DTR2G include internal ESD protection diodes?

The 74HC04DTR2G features built-in ESD protection rated to 2000 V HBM and 200 V Machine Model, per JEDEC Std. 7A. It does not contain forward-biased input clamping diodes to VCC or GND; therefore, input voltages must remain within –0.5 V to VCC + 0.5 V to avoid damage.

What is the thermal resistance (θJA) of the 74HC04DTR2G in TSSOP-14 package?

The 74HC04DTR2G in TSSOP-14 (Case 948G) has a junction-to-ambient thermal resistance (θJA) of 160°C/W under standard JEDEC test conditions (1s² copper pad, no airflow). Derating is –6.1 mW/°C above 65°C ambient, limiting max continuous power dissipation to ~450 mW at 125°C case temperature.
