onsemi MM74HC00SJX

Overview

MM74HC00SJX from ON Semiconductor is a quad 2-input NAND gate in 14-lead SOP (EIAJ TYPE II, 5.3mm wide) packaging, fabricated using advanced silicon-gate CMOS technology. It operates across 2V–6V supply, delivers 8ns typical propagation delay at 6V, supports –40°C to +85°C industrial temperature range, and drives up to 10 LS-TTL loads - used in digital logic control, address decoding, and enable/disable circuitry for microcontroller peripherals.

For engineers reviewing the MM74HC00SJX datasheet, pinout, applications, or equivalent options, key selection criteria include supply voltage flexibility (2–6V), guaranteed 15ns max propagation delay at 4.5V, low 20µA max quiescent current, buffered outputs with high noise immunity, and functional/pin-out compatibility with 74LS logic families.

Technical Context

The MM74HC00SJX implements four independent 2-input NAND gates with fully buffered CMOS outputs, enabling clean signal transitions and stable fanout loading. Its internal diode clamps on all inputs provide ESD protection to V_CC and ground, and it maintains consistent logic thresholds across its full 2V–6V operating range.

This device belongs to the 74HC high-speed CMOS family, designed as a direct functional and pin-compatible replacement for 74LS00 while delivering significantly lower power consumption. It meets JEDEC MO-153 mechanical standards for SOP packages and complies with J-STD-020B for lead-free reflow profiles.

Key Specifications

FAQ

What is the maximum propagation delay of the MM74HC00SJX at 5V supply?

The MM74HC00SJX has a guaranteed maximum propagation delay of 15ns at V_CC = 4.5V, CL = 50pF, and TA = –40°C to +85°C. At exactly 5.0V, the datasheet specifies 18ns max under the same conditions - this value reflects worst-case timing across temperature and process variation, and must be used for setup/hold timing analysis in synchronous designs using the MM74HC00SJX.

Is the MM74HC00SJX pin-compatible with the 74LS00?

Yes, the MM74HC00SJX is functionally and pin-out compatible with the 74LS00. All four NAND gates occupy identical pin positions (e.g., inputs on pins 1&2, output on pin 3), and the power/ground pins (7 and 14) match. This allows direct replacement in existing 74LS00-based PCB layouts without modification - a key design advantage confirmed in the MM74HC00 datasheet Rev. 1.3.0.

Does the MM74HC00SJX require external pull-up resistors on inputs?

No, the MM74HC00SJX does not require external pull-up resistors on inputs. Its CMOS inputs have extremely low leakage (±1.0µA max), and internal structure provides defined logic states when left unconnected only in non-noisy, static environments. However, for robust industrial use, ON Semiconductor recommends tying unused inputs to V_CC or GND - not floating - to prevent oscillation and EMI; the MM74HC00SJX itself contains no internal pull-ups.

What is the recommended PCB land pattern for MM74HC00SJX?

The MM74HC00SJX requires the EIAJ TYPE II SOP land pattern per standard SOP65P640X110-14M: 0.65mm pitch, 1.65mm pad length, 0.45mm pad width, 5.60mm body width, and 8.75mm body length. This pattern ensures reliable solder joint formation during reflow and matches the mechanical drawing MKT-M14DrevX referenced in the MM74HC00 datasheet for the SJ package variant.

Can the MM74HC00SJX operate reliably at 2.0V supply?

Yes, the MM74HC00SJX is fully specified down to 2.0V supply: propagation delay is 45ns max, output drive is ±20µA, and input thresholds are VIH = 1.5V / VIL = 0.5V - providing >1.0V noise margin. This makes the MM74HC00SJX suitable for single-cell Li-ion or 2xAA battery-powered systems where regulated 3.3V is unavailable, as confirmed in the Recommended Operating Conditions table of the MM74HC00 Rev. 1.3.0 datasheet.
