onsemi MM74HC00MTC

Overview

MM74HC00MTC from ON Semiconductor is a quad 2-input NAND gate in the 74HC CMOS logic family, operating across 2V–6V supply, delivering 8ns typical propagation delay at 6V, fanout of 10 LS-TTL loads, and buffered outputs for noise-immune digital control in industrial timing and interface circuits.

For engineers reviewing the MM74HC00MTC datasheet, pinout, applications, or equivalent options, key selection criteria include its TSSOP-14 package compatibility with high-density PCB layouts, guaranteed 15ns max propagation delay over –40°C to +85°C, low 20µA max quiescent current, and functional/pin-out compatibility with 74LS00.

Technical Context

The MM74HC00MTC implements four independent NAND gates using silicon-gate CMOS technology, achieving LS-TTL speed with CMOS power efficiency. All inputs feature diode clamps to V_CC and GND for ESD protection, and all outputs are fully buffered to ensure consistent drive strength and signal integrity.

It operates within a wide 2V–6V V_CC range and supports input rise/fall times up to 1000ns at 2V, enabling robust interfacing with legacy TTL and mixed-voltage systems. Its logic levels (VIH = 3.15V min at 4.5V, VIL = 1.35V max) ensure reliable switching in noisy industrial environments.

FAQ

What is the maximum operating supply voltage for MM74HC00MTC?

The MM74HC00MTC supports a recommended operating supply voltage range of 2V to 6V, with an absolute maximum V_CC rating of +7.0V. Operation above 6V is not recommended and may compromise reliability or parametric performance. The MM74HC00MTC is fully specified and tested at 6V, delivering guaranteed 15ns max propagation delay and 4.0mA output drive under those conditions.

Is MM74HC00MTC pin-compatible with the 74LS00?

Yes, the MM74HC00MTC is functionally and pin-out compatible with the 74LS00, including identical pin assignments for all four NAND gates, V_CC, and GND. This allows direct replacement in existing 74LS00 designs without PCB modification, while providing lower power consumption and improved noise immunity. The MM74HC00MTC retains the same logic truth table and timing behavior required for drop-in migration.

What is the input capacitance specification for MM74HC00MTC?

The MM74HC00MTC has a maximum input capacitance (C_IN) of 10pF per input pin, measured at 25°C. This low value minimizes capacitive loading on driving sources and supports high-speed signal integrity in dense logic arrays. The MM74HC00MTC's 10pF C_IN contributes to its ability to maintain fast rise/fall times even when driving multiple downstream inputs.

Does MM74HC00MTC include ESD protection on its inputs?

Yes, the MM74HC00MTC integrates internal diode clamps on all inputs connected to V_CC and GND, rated for ±20mA clamp current. These clamps provide inherent protection against electrostatic discharge events up to ±2kV HBM, eliminating the need for external ESD suppression components in most industrial applications. This feature is explicitly documented in the Absolute Maximum Ratings and General Description sections of the MM74HC00MTC datasheet.

What is the guaranteed propagation delay for MM74HC00MTC over temperature?

The MM74HC00MTC guarantees a maximum propagation delay (t_PHL/t_PLH) of 15ns at V_CC = 6V and CL = 50pF over the full industrial temperature range of –40°C to +85°C. At 4.5V, the guaranteed max delay is 18ns, and at 2.0V it rises to 90ns - all values are explicitly specified in the AC Electrical Characteristics table of the official MM74HC00MTC datasheet.
