Product details
Overview
MM74HC08SJ from ON Semiconductor is a quad 2-input AND gate in EIAJ TYPE II SOP-14 package, operating from 2V to 6V supply, with typical propagation delays of 7ns (tPLH) and 12ns (tPHL), fanout of 10 LS-TTL loads, and quiescent current ≤2µA at room temperature - used for digital logic control in industrial interface modules.
For engineers reviewing the MM74HC08SJ datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, package dimensions, real-world use cases, and validated alternative parts for logic-level signal conditioning and combinational gating in space-constrained PCB designs.
Technical Context
The MM74HC08SJ implements four independent 2-input AND gates using silicon-gate CMOS technology, delivering LS-TTL-compatible speed with CMOS power efficiency. All inputs feature diode clamps to VCC and GND for ESD protection, and outputs are fully buffered for high noise immunity.
It belongs to the 74HC logic family, ensuring functional and pin-out compatibility with 74LS devices. Operating across –40°C to +85°C, it supports rail-to-rail input voltage (0 to VCC) and drives ±4mA per output at 4.5V while maintaining VOL ≤0.33V and VOH ≥3.98V.
Key Specifications

|---|---|
Use Scenario: Adding discrete logic gating to enable/disable sensor readout channels based on system mode. IC Role / Device Role / Timing Role: Quad AND gate performing level-sensitive enable logic for analog multiplexer selection and ADC sampling windows.

Use Value: Avoids inrush current conflicts and bus contention without requiring dedicated sequencer IC. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2-input AND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HC08DR | Same 74HC logic family, SOIC-14 package, identical AC/DC specs; TI part has tighter tPLH/tPHL distribution (10/13ns typ) | No functional difference; compatible in all 74HC-based designs | Select when sourcing from TI-authorized channels or requiring TI-specific qualification documentation |
| 74VHC08M | Higher speed (tPLH/tPHL = 5.5/6.5ns @ 5V), lower CPD (22pF), but reduced noise margin (VIH min = 3.0V @ 4.5V) | Better for high-frequency clock gating; less tolerant of noisy supply or marginal input thresholds | Prefer for timing-critical paths where propagation delay <6ns is required and supply stability is assured |
Compared with SN74HC08DR and 74VHC08M, the MM74HC08SJ offers balanced speed-power-noise performance ideal for general-purpose industrial logic, with broader input voltage tolerance and higher noise immunity than VHC variants, and identical interoperability with legacy 74LS designs as the TI part.

FAQ
What is the maximum supply voltage rating for MM74HC08SJ?
The MM74HC08SJ has an absolute maximum supply voltage (VCC) rating of +7.0V, but its recommended operating range is 2.0V to 6.0V. Operation above 6.0V risks exceeding internal oxide breakdown limits and is not guaranteed for functionality or reliability. For sustained operation, maintain VCC ≤6.0V per the Recommended Operating Conditions table in the datasheet.
Does MM74HC08SJ support 3.3V logic systems?
Yes, the MM74HC08SJ operates reliably at 3.3V supply: VIH(min) = 2.0V and VIL(max) = 0.99V at VCC = 3.3V (interpolated from 2.0V/4.5V data), providing >1.3V noise margin. Its output VOH ≥3.1V and VOL ≤0.33V at 3.3V/4mA ensure clean interfacing with standard 3.3V CMOS and LVTTL inputs.
Is MM74HC08SJ pin-compatible with 74LS08?
Yes, the MM74HC08SJ is pin-out compatible with the 74LS08 - both use 14-pin DIP/SOIC packages with identical pin assignments for inputs, outputs, VCC, and GND. This allows direct replacement in existing 74LS designs without PCB modification, provided supply voltage and load conditions align with HC specifications.
What is the thermal resistance (θJA) for MM74HC08SJ in SOP-14 package?
The MM74HC08SJ in EIAJ TYPE II SOP-14 (M14D) package has a typical junction-to-ambient thermal resistance (θJA) of 120°C/W under standard JEDEC test board conditions (1-inch² copper pad). Actual θJA depends on PCB layout; adding thermal vias and copper pour can reduce it to ~60°C/W in optimized designs.
Can MM74HC08SJ drive LEDs directly?
Yes, MM74HC08SJ can drive standard 2mA indicator LEDs directly when configured in active-low mode (output LOW to sink current): at VCC = 5V, it guarantees 4.0mA sink capability with VOL ≤0.33V, yielding ~4.7V across a 2.2kΩ current-limiting resistor. For higher brightness or multiple LEDs, add a transistor buffer to avoid exceeding output current limits.
