Product details
Overview
74ACT11032DBRG4 from Texas Instruments is a quadruple 2-input positive-OR gate logic IC in 16-pin SSOP (DB) package, fabricated using EPIC 1-µm CMOS process. It operates from –40°C to 85°C at 4.5–5.5 V supply, delivers ±24 mA output drive, and features TTL-voltage-compatible inputs with 1.5 ns typical propagation delay (tPLH/tPHL). It is used in digital control logic, bus arbitration, and signal combining in industrial and telecom interface circuits.
For engineers reviewing the 74ACT11032DBRG4 datasheet, 74ACT11032DBRG4 pinout, 74ACT11032DBRG4 application, or 74ACT11032DBRG4 equivalent, key selection criteria include guaranteed 24-mA drive strength at 5 V, low 29-pF power-dissipation capacitance per gate, center-pin VCC/GND layout for noise suppression, and compatibility with legacy 74ACT logic families in space-constrained board designs.
Technical Context
The 74ACT11032DBRG4 implements four independent OR gates (Y = A + B) in positive logic, with input thresholds aligned to TTL voltage levels (VIL ≤ 0.8 V, VIH ≥ 2 V) while operating on a 5-V CMOS supply. Its EPIC process ensures latch-up immunity of 500 mA at 125°C and robust ESD tolerance.
Designed for high-speed digital systems, it uses center-aligned VCC (Pin 16) and GND (Pin 8) pins to minimize simultaneous switching noise. Switching characteristics are specified across temperature and supply voltage, with tPLH/tPHL ranging from 1.5 ns (min) to 9 ns (max) at 25°C and 5 V.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2-input OR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ACT32DBR | Same 16-pin SSOP package, identical electrical specs (±24 mA, 1.5–9 ns), but marked as "ACTIVE" with full TI production support. | No functional or layout difference; SN74ACT32DBR is the modern rebranded part number for same silicon. | Select SN74ACT32DBR for new designs requiring long-term availability and TI's latest quality documentation. |
| 74ACT32D | SOIC-16 (D package) instead of SSOP-16 (DB); 40-unit tape-and-reel vs. TBD quantity for DB variant. | Larger footprint (10.2 mm × 6.2 mm vs. 6.2 mm × 5.3 mm); higher thermal resistance (1.3 W max vs. 0.55 W). | Choose 74ACT32D only if board layout lacks SSOP clearance or requires higher power dissipation headroom. |
Compared with 74ACT11032DBRG4, SN74ACT32DBR offers identical performance in the same package with stronger long-term supply assurance, while 74ACT32D trades compactness for easier hand-soldering and higher power handling - selection depends on board density, thermal budget, and procurement lifecycle requirements.

FAQ
What logic family does the 74ACT11032DBRG4 belong to, and how does it differ from standard 74HC logic?
The 74ACT11032DBRG4 belongs to Texas Instruments' Advanced CMOS Technology (ACT) family. Unlike 74HC, it features TTL-compatible input thresholds (VIH ≥ 2 V, VIL ≤ 0.8 V), higher output drive (±24 mA vs. ±4 mA for 74HC), and faster propagation (1.5–9 ns vs. ~15 ns typical for 74HC32). The 74ACT11032DBRG4 maintains 5-V operation while delivering LSTTL fan-out capability without level shifters.
Is the 74ACT11032DBRG4 pin-compatible with the older 74F32 or 74LS32?
Yes - the 74ACT11032DBRG4 shares identical pinout and Boolean functionality with 74F32 and 74LS32 in 16-pin packages. Its TTL-compatible inputs and 5-V supply allow direct replacement in existing designs. However, note that 74ACT11032DBRG4 draws lower quiescent current than 74F32 and offers superior noise immunity due to its center-pin VCC/GND layout.
What is the maximum allowable output current per pin for the 74ACT11032DBRG4, and under what conditions is it specified?
The 74ACT11032DBRG4 specifies ±24 mA DC output current per pin under recommended operating conditions (VCC = 4.5–5.5 V, TA = –40°C to 85°C), with VOH ≥ 3.94 V and VOL ≤ 0.44 V at 5 V. This rating applies to steady-state DC drive - transient peak currents (e.g., during switching) are limited by internal structure and thermal constraints, not absolute maximum ratings.
Does the 74ACT11032DBRG4 require external decoupling capacitors, and if so, where should they be placed?
Yes - a 0.1-µF ceramic capacitor is recommended between VCC (Pin 16) and GND (Pin 8), placed as close as possible to those pins. The center-aligned VCC/GND configuration of the 74ACT11032DBRG4 is specifically optimized for low-inductance decoupling; placing the capacitor within 2 mm of both pins minimizes high-frequency loop inductance and suppresses simultaneous switching noise.
What is the meaning of "EPIC" in the 74ACT11032DBRG4 datasheet, and how does it affect device reliability?
EPIC stands for Enhanced-Performance Implanted CMOS - TI's proprietary 1-µm fabrication process. It provides 500-mA typical latch-up immunity at 125°C, significantly exceeding standard CMOS. This makes the 74ACT11032DBRG4 highly robust in electrically noisy industrial environments where transient-induced latch-up could otherwise disrupt system operation.
