onsemi MM74HC04MTC

Overview

MM74HC04MTC from onsemi is a hex inverter IC in the 74HC logic family, implementing six independent CMOS inverters in a single TSSOP-14 package. It operates from 2 V to 6 V, delivers 8 ns typical propagation delay at 5 V, drives up to 10 LS-TTL loads, and supports industrial temperature range (–55°C to +125°C) - used for signal inversion, level translation, and clock buffering in digital control subsystems.

For engineers reviewing the MM74HC04MTC datasheet, pinout, applications, or equivalent options, key selection criteria include supply voltage range, propagation delay under load, output drive capability, input noise immunity, and RoHS-compliant TSSOP packaging for high-density PCB layouts.

Technical Context

The MM74HC04MTC uses silicon-gate CMOS technology to achieve LS-TTL speed with CMOS power efficiency. Each of its six gates features buffered output stages, internal input clamping diodes to V_CC and GND, and guaranteed rail-to-rail input voltage tolerance (–0.5 V to V_CC + 0.5 V).

It is functionally and pin-out compatible with the 74LS04 but offers lower quiescent current (≤40 µA at 6 V), higher noise immunity, and wider operating voltage (2–6 V vs. 4.75–5.25 V for LS). AC performance is specified across three temperature ranges and multiple V_CC levels, with worst-case t_PLH/t_PHL of 24 ns at 6 V and –55°C to +125°C.

FAQ

What is the maximum operating temperature for the MM74HC04MTC?

The MM74HC04MTC is rated for continuous operation from –55°C to +125°C. This specification is validated per onsemi's recommended operating conditions and absolute maximum ratings tables, with guaranteed AC/DC performance across the full range. The MM74HC04MTC maintains 24 ns worst-case propagation delay and 40 µA max ICC even at +125°C, making it suitable for under-hood automotive and industrial motor drive applications.

Does the MM74HC04MTC require external pull-up or pull-down resistors on unused inputs?

Yes - unused inputs on the MM74HC04MTC must be terminated to V_CC or GND. Floating CMOS inputs can cause increased power consumption, oscillation, or latch-up due to intermediate voltage states. The MM74HC04MTC has no internal pull-ups or pull-downs; each of its six inverters requires explicit biasing. For example, tie unused A1 to GND via a 10 kΩ resistor to ensure stable Y1 = HIGH and prevent shoot-through current.

Can the MM74HC04MTC drive a 50 pF capacitive load at 10 MHz?

The MM74HC04MTC can drive a 50 pF load, but not reliably at 10 MHz. At V_CC = 5 V and C_L = 50 pF, the datasheet specifies t_PLH/t_PHL ≤ 19 ns (TA = –40°C to +85°C) and t_THL/t_TLH ≤ 15 ns - resulting in minimum pulse width ~76 ns, limiting max frequency to ~6.6 MHz. For 10 MHz operation, reduce C_L to ≤25 pF or add a buffer stage. The MM74HC04MTC's CPD = 20 pF also implies dynamic current rise at higher frequencies.

Is the MM74HC04MTC pin-compatible with the SN74HC04N in DIP-14 packages?

No - the MM74HC04MTC (TSSOP-14) and SN74HC04N (DIP-14) share identical logic function and pin numbering (1–14), but differ in physical dimensions, lead pitch (0.65 mm vs. 2.54 mm), and thermal characteristics. While electrical pinout matches, PCB layout, soldering process, and mechanical mounting are incompatible. The MM74HC04MTC cannot be substituted into a DIP socket or through-hole design without redesign.

What is the input leakage current specification for the MM74HC04MTC at 6 V?

The MM74HC04MTC has a maximum input leakage current (I_IN) of ±1.0 µA at V_CC = 6 V and T_A = –55°C to +125°C, per the DC Characteristics table. This value is measured with inputs biased to V_CC or GND. At room temperature (25°C), typical I_IN is <0.1 µA. This low leakage ensures minimal loading on high-impedance sources such as RC timing networks or sensor output buffers feeding the MM74HC04MTC.
