Product details

Overview

MM74HCT00M from onsemi is a quad 2-input NAND gate IC fabricated in advanced silicon-gate CMOS technology, providing TTL/LS pinout and threshold compatibility, 14 ns typical propagation delay (tPLH/tPHL), ±25 mA DC output current per pin, and operation across −55°C to +125°C. It serves as a logic-level translator and power-efficient replacement for 74LS00 in industrial control and embedded interface circuits.

For engineers reviewing the MM74HCT00M datasheet, pinout, applications, or equivalent options, this page delivers verified package mapping (TSSOP-14, Case 948G), confirmed static/dynamic electrical specs, thermal operating limits, and real-world substitution guidance - all traceable to onsemi's April 2025 Rev. 3 datasheet.

Technical Context

The MM74HCT00M implements four independent 2-input NAND gates in a single monolithic CMOS die, with input clamp diodes to VCC and GND for ESD protection. Its input thresholds (VIH = 2.0 V min, VIL = 0.8 V max) and output drive capability (VOH ≥ 3.7 V at 4.0 mA, VOL ≤ 0.4 V at 4.0 mA) ensure reliable interfacing between TTL, LS-TTL, and CMOS systems.

Designed for mixed-logic environments, the device operates from 4.5 V to 5.5 V with quiescent ICC ≤ 40 µA over full temperature range and supports dynamic loading up to 10 LS-TTL loads. AC performance is characterized at CL = 15 pF and CL = 50 pF, with guaranteed tPLH/tPHL ≤ 35 ns at −55°C to +125°C.

Key Specifications

Equivalent & Alternatives

The following parts are listed as comparable options for similar NAND gate applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74HCT00DR	SOIC-14 package (5.3 mm × 6.2 mm), slightly higher ICC (≤50 µA), identical AC/DC specs and pinout.	Preferred where manual soldering, through-hole prototyping, or legacy SOIC footprints are used.	Select SN74HCT00DR when board space allows larger package and hand-soldering is required during NPI or repair.
74VHC00M	Higher speed (tPLH/tPHL ≤ 7.5 ns typ.), wider VCC range (2 V–5.5 V), but lower drive (±8 mA) and no guaranteed −55°C operation.	Suitable for high-speed consumer or communications logic where extended temperature range is not required.	Choose 74VHC00M only if >15 MHz toggle rates are needed and industrial temperature qualification is unnecessary.

Compared with SN74HCT00DR and 74VHC00M, the MM74HCT00M uniquely balances TSSOP-14 miniaturization, −55°C to +125°C qualification, and ±25 mA drive - making it optimal for space-constrained, thermally demanding industrial and automotive control nodes where reliability trumps raw speed.

FAQ

What is the maximum operating temperature range for MM74HCT00M?

The MM74HCT00M is fully specified and guaranteed to operate from −55°C to +125°C, as confirmed in the Absolute Maximum Ratings and Recommended Operating Conditions tables of the onsemi datasheet (Rev. 3, April 2025). This range applies to both DC and AC parameters, including propagation delay and output drive capability, making MM74HCT00M suitable for under-hood automotive and industrial environments where ambient temperatures exceed 105°C.

Is MM74HCT00M pin-compatible with standard 74LS00 devices?

Yes, the MM74HCT00M features identical pin assignments, input thresholds, and output drive characteristics to the 74LS00, as explicitly stated in the General Description section of the onsemi datasheet. Its TTL/LS pinout and threshold compatibility allow direct replacement without PCB modification - verified across all 14 pins of the TSSOP-14 package, including VCC (pin 14), GND (pin 7), and all input/output terminals.

What is the typical propagation delay of MM74HCT00M at 5 V and 25°C?

The MM74HCT00M exhibits a typical propagation delay (tPLH and tPHL) of 14 ns at VCC = 5.0 V, tr/tf = 6 ns, and CL = 15 pF, per the AC Electrical Characteristics table in the onsemi datasheet. This value is measured under controlled lab conditions and represents the average switching performance across all four gates in the device.

Does MM74HCT00M support 3.3 V logic interfacing?

No - the MM74HCT00M is designed for 5 V operation only, with a minimum supply voltage of 4.5 V and guaranteed performance only within 4.5 V to 5.5 V. Its input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) are optimized for 5 V TTL compatibility; interfacing directly with 3.3 V logic requires level-shifting circuitry, as the MM74HCT00M does not support dual-supply or mixed-voltage operation.

What package type is used for MM74HCT00M?

The MM74HCT00M is supplied exclusively in the TSSOP-14 wide-body package (Case 948G), as confirmed by the Ordering Information table and mechanical drawings in the onsemi datasheet. This package measures 5.0 mm × 4.4 mm with 0.65 mm lead pitch, Pb-free and halide-free, and is distinct from SOIC-14 or PDIP variants offered for other members of the HCT family.
