Product details

Overview

DM74AS10 from Fairchild Semiconductor is a triple 3-input NAND gate IC in a 14-lead PDIP package, delivering TTL-compatible logic with 1 ns minimum propagation delay (tPLH/tPHL), 20 mA sink current (IOL), and guaranteed operation from 0°C to +70°C - used in digital control logic, address decoding, and bus interface circuits.

For engineers reviewing the DM74AS10 datasheet, pinout, applications, or equivalent options, key selection considerations include its 50 pF load switching performance, Schottky-TTL process compatibility, VCC = 4.5–5.5 V operating range, and functional equivalence to standard 74-series triple NANDs in legacy digital systems.

Technical Context

The DM74AS10 integrates three independent 3-input NAND gates on a single die using oxide-isolated, ion-implanted Schottky TTL technology - enabling high-speed switching with low input current (IIL = −0.5 mA, IIH = 20 µA) and robust noise immunity (VIL = 0.8 V, VIH = 2 V).

It operates strictly within 4.5–5.5 V supply range and supports fan-out of up to 20 LS-TTL loads; output drive capability includes 20 mA sink (IOL) and 2 mA source (IOH), with VOH ≥ VCC − 2 V and VOL ≤ 0.5 V at full load.

Key Specifications

Parameter	Value and Actual Design Meaning
VCC Range	4.5 V to 5.5 V - ensures stable operation across standard TTL power rails with margin for ripple and tolerance.
tPLH / tPHL	1 ns (min) to 4.5 ns (max) at CL = 50 pF - enables sub-5 ns propagation in high-speed combinational logic paths.
IOL / IOH	20 mA sink / −2 mA source - drives standard TTL inputs directly without buffering in mixed-logic systems.
VIL / VIH	0.8 V / 2.0 V - provides 0.4 V noise margin against TTL-level interference under worst-case conditions.
Operating Temp	0°C to +70°C - qualified for commercial-grade industrial control and instrumentation environments.
ICC (Outputs LOW)	8.1–13 mA - reflects higher dynamic current draw during active-state switching, critical for power budgeting.

Pinout & Package

DM74AS10 is housed in a 14-lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300" wide, with through-hole mounting and industry-standard footprint.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3	Input A/B/C of Gate 1	Three independent logic inputs for first NAND gate; all must be HIGH to assert LOW output.
4	Output Y1	Active-low output of Gate 1; sinks up to 20 mA when LOW, sources up to 2 mA when HIGH.
5, 6, 7	Input A/B/C of Gate 2	Inputs for second independent 3-input NAND function; electrically isolated from other gates.
8	GND	Ground reference for all internal circuitry and I/O; requires low-impedance connection to minimize noise coupling.
9, 10, 11	Input A/B/C of Gate 3	Inputs for third NAND gate; identical electrical characteristics and timing as Gates 1 and 2.
12	Output Y3	Output of Gate 3; shares same DC/AC specs as Y1 and Y2; no internal cross-talk between outputs.
13	Output Y2	Output of Gate 2; placed adjacent to Y3 for compact routing in multi-gate logic blocks.
14	VCC	+5 V supply pin; decoupling capacitor (0.1 µF) recommended within 1 cm for stable high-speed operation.

Key Features

Feature	Design Value
Triple 3-input NAND structure	Three fully independent logic gates in one package - reduces board space and interconnect count vs discrete gate arrays.
Oxide-isolated Schottky TTL process	Enables 1 ns min propagation delay while maintaining TTL voltage compatibility and noise margins.
Guaranteed AC specs over full temp/VCC	Switching parameters validated from 0°C to +70°C and 4.5–5.5 V - eliminates derating calculations in commercial designs.
Pin-for-pin compatible with 74S10/74LS10/74ALS10	Direct drop-in replacement in existing layouts using standard 14-pin DIP footprints and signal assignments.

Equivalent & Alternatives

The following parts are listed as comparable options for similar triple 3-input NAND gate applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74AS10N	Identical pinout, AC/DC specs, and package; manufactured by Texas Instruments with same AS-series Schottky process.	No functional or layout change required; suitable for dual-sourcing in long-lifecycle industrial programs.	Select SN74AS10N when TI's supply chain assurance or extended product longevity commitments are prioritized.
74F10N	Fast TTL variant: faster tPLH/tPHL (typ. 2.5 ns), lower ICC (3.5 mA), but reduced IOL (12 mA) and narrower VCC range (4.75–5.25 V).	Better suited for speed-critical clocked logic; not recommended where 20 mA drive or wide VCC margin is required.	Choose 74F10N only if propagation delay dominates design constraints and output loading remains ≤12 mA.

Compared with SN74AS10N and 74F10N, the DM74AS10 offers the broadest VCC tolerance (4.5–5.5 V) and highest sink current (20 mA), making it optimal for legacy system upgrades and mixed-load digital interfaces where robustness outweighs marginal speed gains.

FAQ

What logic function does the DM74AS10 implement?

The DM74AS10 implements three independent 3-input NAND logic functions - each gate outputs LOW only when all three inputs are HIGH. This Boolean behavior (Y = ABC) is defined in the device's function table and verified across its full operating range of 0°C to +70°C and VCC = 4.5–5.5 V. The DM74AS10 maintains consistent truth table operation regardless of input transition order or load conditions.

Is the DM74AS10 pin-compatible with other 74-series triple NAND gates?

Yes, the DM74AS10 is pin-for-pin compatible with 74S10, 74LS10, and 74ALS10 devices in the same 14-lead PDIP package. All share identical pin assignments for inputs, outputs, VCC, and GND. This allows direct substitution in existing PCB layouts without modification, provided the system's timing and drive requirements align with the DM74AS10's 1–4.5 ns propagation and 20 mA sink capability.

What is the maximum capacitive load the DM74AS10 can drive while meeting timing specs?

The DM74AS10's switching characteristics are guaranteed at CL = 50 pF, as specified in the datasheet's "Switching Characteristics" table. Driving loads beyond 50 pF may increase propagation delay beyond the 4.5 ns maximum and degrade noise margins. For heavier loads, external buffer stages or layout optimization (shorter traces, reduced parallel capacitance) is recommended to maintain DM74AS10 timing integrity.

Does the DM74AS10 support operation outside the 0°C to +70°C range?

No - the DM74AS10 is rated only for 0°C to +70°C free-air operating temperature. Its electrical characteristics, including propagation delay, output voltage levels, and current drive, are not guaranteed outside this range. Attempting operation below 0°C or above +70°C risks timing violations, increased ICC, or functional failure. For extended temperature applications, consider automotive-qualified alternatives such as the SN74AS10QDR.

How does the DM74AS10 handle unused inputs?

Unused inputs on the DM74AS10 must be tied to a valid logic level - either VCC (for HIGH) or GND (for LOW) - to prevent floating nodes that cause excessive power consumption, oscillation, or unpredictable output states. Leaving inputs unconnected violates the device's recommended operating conditions and may result in erratic behavior, especially under temperature or voltage variation. Each of the three gates' unused inputs should be terminated individually per application requirements.
