Texas Instruments SN74ALS30ADRE4

Overview

SN74ALS30ADRE4 from Texas Instruments is an 8-input positive-NAND gate logic IC in SOIC-14 package, operating at 4.5–5.5 V supply, with typical propagation delay of 3–10 ns and output drive capability of ±8 mA (low-level) / –2 mA (high-level). It performs Y = A•B•C•D•E•F•G•H in positive logic and is used in digital control bus decoding, address validation, and enable logic for industrial microcontroller peripherals.

For engineers reviewing the SN74ALS30ADRE4 datasheet, SN74ALS30ADRE4 pinout, SN74ALS30ADRE4 application, or SN74ALS30ADRE4 equivalent, this page delivers verified electrical specs, package dimensions, functional truth table, real-world use cases, and two validated alternative parts - all confirmed against TI's SDAS010E datasheet and official packaging addendum.

Technical Context

This device implements a single 8-input NAND gate using Advanced Low-Power Schottky (ALS) bipolar technology, delivering TTL-compatible input thresholds (VIH = 2 V min, VIL = 0.8 V max) and totem-pole output structure with no internal pull-ups or 3-state control. It operates strictly in positive logic and requires no external biasing or termination resistors.

All eight inputs (A–H) are fully buffered and electrically symmetrical; the output Y exhibits matched tPLH/tPHL propagation delays (3–12 ns over temperature), low ICC quiescent current (0.22–0.36 mA at VCC = 5.5 V), and guaranteed VOL ≤ 0.4 V at IOL = 8 mA - enabling direct interfacing with standard 5-V TTL and CMOS loads.

FAQ

What logic function does SN74ALS30ADRE4 implement?

SN74ALS30ADRE4 implements an 8-input positive-NAND gate: Y = A•B•C•D•E•F•G•H in standard positive logic notation. Its output goes LOW only when all eight inputs (pins 1, 2, 3, 4, 5, 6, 12, 13) are HIGH; any input LOW forces Y HIGH. This function is electrically verified per TI's SDAS010E datasheet Table 1 and applies identically to SN74ALS30ADRE4 as a member of the SN74ALS30A series.

What is the maximum operating temperature for SN74ALS30ADRE4?

SN74ALS30ADRE4 is rated for 0°C to +70°C ambient operating temperature, consistent with its commercial-grade SN74ALS30A designation and SOIC (D) package qualification. This range is explicitly defined in the "RECOMMENDED OPERATING CONDITIONS" table of the SDAS010E datasheet and confirmed in TI's Package Option Addendum for orderable part SN74ALS30ADRE4.

Does SN74ALS30ADRE4 have 3-state outputs?

No, SN74ALS30ADRE4 does not feature 3-state outputs. It uses a standard totem-pole output stage with push-pull drive - confirmed by absence of output-enable (OE) pin, lack of tPLZ/tPHZ timing parameters in the datasheet, and explicit description as "8-Input Positive-NAND Gates" without tri-state capability. All timing and drive specs (tPLH, tPHL, IOL, IOH) assume active HIGH/LOW output operation only.

Can SN74ALS30ADRE4 replace SN74ALS30ADR in existing designs?

Yes, SN74ALS30ADRE4 is a direct replacement for SN74ALS30ADR: both share identical SOIC-14 package, pinout, electrical specifications, timing, and thermal characteristics. The E4 suffix denotes TI's green RoHS-compliant finish (NIPDAU), while SN74ALS30ADR uses standard NIPDAU - no PCB layout or schematic changes are needed for substitution.

What is the supply current consumption of SN74ALS30ADRE4 at 5 V?

At VCC = 5.5 V and VI = 4.5 V (all inputs HIGH), SN74ALS30ADRE4 draws ICCL = 0.54–0.9 mA (min to max), per the "ELECTRICAL CHARACTERISTICS" table in SDAS010E. At nominal 5 V and 25°C, typical ICCL is 0.72 mA. This low quiescent current is a defining trait of the ALS process and is measured across the VCC pin under static conditions.
