Product details
Overview
DM74AS00M from Fairchild Semiconductor is a quad 2-input NAND gate IC implemented in advanced oxide-isolated, ion-implanted Schottky TTL technology. It delivers guaranteed switching performance at 50 pF load across 0°C to +70°C and 4.5V–5.5V VCC, with tPLH/tPHL as low as 1 ns (typ), IOL = 20 mA, and VOH ≥ VCC − 2 V - used in high-speed digital logic interfacing and control signal conditioning.
For engineers reviewing the DM74AS00M datasheet, pinout, applications, or equivalent options, key selection criteria include propagation delay under 4.5 ns max, output drive capability of 20 mA sink current, input voltage thresholds (VIL ≤ 0.8 V, VIH ≥ 2.0 V), and SOIC-14 JEDEC MS-012 package compatibility with automated SMT assembly.
Technical Context
The DM74AS00M integrates four independent NAND gates on a single die using Schottky-clamped bipolar transistor architecture, enabling fast transition times without saturation delay. Its logic function Y = AB is strictly combinatorial with no internal latching or clocking.
It operates exclusively within TTL-compatible voltage domains: inputs accept standard TTL thresholds, outputs drive standard TTL loads, and it requires a single 5 V supply with ICC ranging from 2.2 mA (all outputs HIGH) to 17.4 mA (all outputs LOW) at VCC = 5.5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 4.5 V to 5.5 V - ensures compatibility with standard 5 V TTL power rails and tolerance to supply ripple. |
| tPLH / tPHL | 1 ns (typ), 4.5 ns (max) - enables use in >200 MHz clock-domain edge sampling and high-speed bus arbitration logic. |
| IOL / IOH | 20 mA sink / −2 mA source - supports direct driving of multiple standard TTL inputs (fan-out ≥ 20) without buffer stages. |
| VIL / VIH | 0.8 V / 2.0 V - guarantees noise margin >0.4 V under worst-case conditions and interoperability with legacy TTL families. |
| Operating Temp | 0°C to +70°C - qualified for commercial-grade industrial control panels and office equipment environments. |
| Package | SOIC-14, JEDEC MS-012, 0.150" narrow body - surface-mount compatible with 0.050" pitch PCB assembly and reflow profiles. |
Pinout & Package
DM74AS00M is housed in a 14-lead Small Outline Integrated Circuit (SOIC) package per JEDEC MS-012, 0.150" narrow body, with thermal resistance θJA = 114.0°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 8, 9, 11, 12 | Input (A/B per gate) | Four independent NAND gate inputs - pins assigned as A1/B1, A2/B2, A3/B3, A4/B4 per standard dual-in-line pinout mapping. |
| 3, 6, 10, 13 | Output (Y1–Y4) | Open-collector–compatible TTL outputs - each capable of sinking 20 mA while maintaining VOL ≤ 0.5 V. |
| 7 | GND | Ground reference for all logic and power paths - must be low-impedance connection to minimize ground bounce in high-speed switching. |
| 14 | VCC | +5 V supply rail - decoupling capacitor (0.1 µF ceramic) required within 10 mm of this pin for stable AC operation. |
Key Features
| Feature | Design Value |
|---|---|
| Advanced Schottky TTL process | Enables sub-5 ns propagation delay with reduced storage time versus standard TTL, eliminating need for external speed-up capacitors. |
| Guaranteed AC specs at 50 pF | Validates timing performance into typical PCB trace + input capacitance loads without derating - simplifies board-level timing closure. |
| Full temperature/voltage spec coverage | Electrical parameters guaranteed over entire 0°C–70°C and 4.5V–5.5V range - eliminates need for design margining in commercial applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NAND gate logic applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AS00DR | Same AS-family architecture, identical AC/DC specs, SOIC-14 package, TI-branded; VCC min = 4.5 V, tPLH/tPHL max = 4.5 ns. | No functional deviation - validated for same industrial control and bus interface roles. | Select when requiring TI's long-term product continuity program and extended lifecycle support. |
| 74VHC00M | CMOS-based, 2V–5.5V VCC range, lower ICC (< 2 µA), but slower (tPD = 7.5 ns typ), higher noise immunity (VIH = 3.5 V min). | Suitable only where supply voltage flexibility or ultra-low static power matters more than speed. | Choose only if migrating from TTL to CMOS logic families and relaxing timing constraints by ≥2×. |
Compared with SN74AS00DR, DM74AS00M offers identical timing and drive but different manufacturer logistics; versus 74VHC00M, DM74AS00M provides superior speed and TTL compatibility at higher static power - critical for legacy system drop-in replacements.

FAQ
What logic family does the DM74AS00M belong to, and how does it differ from standard TTL?
The DM74AS00M belongs to the 74AS (Advanced Schottky) TTL family. It differs from standard TTL by using Schottky clamping to prevent transistor saturation, resulting in faster switching (1 ns typical propagation delay) and higher output drive (20 mA sink). Unlike 74TTL or 74LSTTL, DM74AS00M guarantees AC performance across full temperature and voltage ranges without derating - a key advantage in stable commercial designs.
Is the DM74AS00M pin-compatible with other 74xx00-series NAND gate packages?
Yes, the DM74AS00M is pin-for-pin compatible with 74S00, 74LS00, and 74ALS00 in the SOIC-14 (M14A) package. Its pinout matches the industry-standard 14-lead dual-in-line configuration: inputs on pins 1/2, 4/5, 8/9, 11/12; outputs on pins 3, 6, 10, 13; VCC on pin 14; GND on pin 7. This allows direct substitution in existing layouts without modification.
What are the absolute maximum ratings for the DM74AS00M, and why do they matter in circuit design?
The DM74AS00M has absolute maximum ratings of 7 V for VCC and input voltage, and −65°C to +150°C for storage temperature. These define electrical and thermal limits beyond which permanent damage may occur. Designers must ensure operating conditions - especially transient overshoot on VCC or inputs - remain below these values. Exceeding them risks junction breakdown or metallization failure, even if DC bias appears nominal.
Can the DM74AS00M drive multiple TTL inputs directly, and how many?
Yes, the DM74AS00M can drive multiple standard TTL inputs directly. With IOL = 20 mA and standard TTL input current IIL = −1.6 mA per gate, each DM74AS00M output supports up to 12 standard TTL loads. Its VOH ≥ VCC − 2 V and VOL ≤ 0.5 V ensure valid logic levels across this fan-out - eliminating need for buffer stages in most industrial control and interface applications using DM74AS00M.
Does the DM74AS00M require external pull-up resistors on its outputs?
No, the DM74AS00M does not require external pull-up resistors. Its outputs are standard TTL totem-pole (push-pull) structures, not open-collector. Each output actively drives both HIGH and LOW states: VOH ≥ VCC − 2 V at IOH = −2 mA, and VOL ≤ 0.5 V at IOL = 20 mA. Pull-ups are unnecessary unless interfacing with non-TTL logic families requiring different voltage thresholds - which is not typical for DM74AS00M applications.
