onsemi DM74ALS10AMX

Overview

DM74ALS10AMX from Fairchild Semiconductor is a triple 3-input NAND gate IC in 14-lead SOIC (M14A) package, operating at 4.5–5.5 V supply, with propagation delays as low as 2 ns (tPLH/tPHL), ±0.4 mA high-level and 8 mA low-level output drive, and guaranteed performance across 0°C to +70°C for digital logic control in industrial timing and bus interface circuits.

For engineers reviewing the DM74ALS10AMX datasheet, pinout, applications, or equivalent options, key selection considerations include its TTL-compatible input thresholds (VIL = 0.8 V, VIH = 2.0 V), 50 pF load switching specs, SOIC-14 thermal resistance (θJA = 116.0°C/W), and functional compatibility with 74S10 and 74LS10 families.

Technical Context

The DM74ALS10AMX implements three independent NAND gates using advanced oxide-isolated, ion-implanted Schottky TTL process, ensuring stable DC and AC performance over full temperature and supply range. Each gate accepts three inputs (A/B/C) and delivers inverted AND logic (Y = ABC) with defined HIGH/LOW output voltage levels under specified load conditions.

It operates strictly within TTL logic voltage domains: VIH ≥ 2.0 V, VIL ≤ 0.8 V, VOH ≥ VCC − 2 V (at IOH = −0.4 mA), and VOL ≤ 0.5 V (at IOL = 8 mA). Propagation delay is characterized at RL = 500 Ω and CL = 50 pF, with tPLH/tPHL ranging 2–11 ns depending on VCC and loading.

Manufacturer

Fairchild Semiconductor was a U.S.-based semiconductor company specializing in analog and mixed-signal ICs, discrete power devices, and logic families before its acquisition by ON Semiconductor in 2016.

The DM74ALS10AMX belongs to Fairchild's Advanced Low-Power Schottky (ALS) TTL logic series, engineered for improved speed-power balance in commercial-grade digital systems where compatibility with legacy TTL infrastructure is essential.

FAQ

What logic family does DM74ALS10AMX belong to, and how does it differ from standard 74LS devices?

DM74ALS10AMX belongs to the Advanced Low-Power Schottky (ALS) TTL family. It delivers faster propagation delays (2–11 ns vs. 15 ns for 74LS10) and lower power consumption (ICC = 0.6 mA typical with outputs HIGH) than standard 74LS devices, while retaining full pin and voltage compatibility. Its oxide-isolated, ion-implanted process enhances reliability and noise immunity over earlier LS and S families. The DM74ALS10AMX remains functionally identical to 74LS10 in truth table and DC behavior.

Is DM74ALS10AMX suitable for operation outside the 0°C to +70°C range?

No. DM74ALS10AMX is specified only for 0°C to +70°C free-air operating temperature, as confirmed in its Recommended Operating Conditions table. Absolute maximum ratings extend to −65°C to +150°C for storage, but electrical characteristics-including propagation delay, output drive, and input thresholds-are not guaranteed outside the commercial temperature range. For extended temperature applications, consider automotive-qualified alternatives or consult manufacturer validation data beyond this datasheet.

What is the maximum capacitive load DM74ALS10AMX can drive while maintaining guaranteed timing?

DM74ALS10AMX switching characteristics-including tPLH and tPHL-are guaranteed at CL = 50 pF, as explicitly stated in the Switching Characteristics table. Driving larger capacitive loads (e.g., >100 pF) will increase propagation delay nonlinearly and may violate setup/hold timing in synchronous systems. For heavier loads, buffer stages or lower-capacitance routing should be used. The DM74ALS10AMX itself does not specify derating curves beyond 50 pF.

Does DM74ALS10AMX require external pull-up or pull-down resistors on unused inputs?

Yes. Unused inputs on DM74ALS10AMX must be terminated to a valid logic level-either VCC (for HIGH) or GND (for LOW)-to prevent floating nodes that cause increased power consumption, oscillation, or unpredictable output states. Leaving inputs unconnected violates the device's recommended operating conditions and risks erratic behavior. This applies equally to all three gates; each unused A/B/C input on DM74ALS10AMX must be actively biased.

Can DM74ALS10AMX be used in place of DM74ALS10AN on the same PCB footprint?

No. DM74ALS10AMX uses SOIC-14 (M14A) packaging, while DM74ALS10AN uses PDIP-14 (N14A). Their footprints are mechanically incompatible: SOIC has gull-wing leads and 1.27 mm pitch; PDIP has through-hole leads and 2.54 mm pitch. Direct substitution requires PCB redesign. However, both share identical pinout numbering and logic functionality-so schematic symbols and net connectivity remain unchanged when migrating from DM74ALS10AN to DM74ALS10AMX with layout revision.
