Product details
Overview
74ACT11032DBRE4 from Texas Instruments is a quadruple 2-input positive-OR gate logic IC in a 16-pin SSOP (DB) package, operating at 4.5–5.5 V supply, delivering 24 mA output drive, 1.5 ns minimum propagation delay, and TTL-voltage-compatible inputs for industrial digital control systems.
For engineers reviewing the 74ACT11032DBRE4 datasheet, 74ACT11032DBRE4 pinout, 74ACT11032DBRE4 application, or 74ACT11032DBRE4 equivalent, this page provides verified functional identity, validated DB-package pin mapping, confirmed switching and DC electrical specs, and two rigorously cross-referenced alternative logic gates for OR-function replacement in legacy 5-V TTL/CMOS hybrid designs.
Technical Context
This device implements four independent 2-input OR gates using Texas Instruments' EPIC (Enhanced-Performance Implanted CMOS) 1-µm process, supporting positive-logic Boolean Y = A + B with guaranteed operation from –40°C to 85°C. Each gate exhibits matched tPLH/tPHL propagation delays and rail-to-rail output swing under 24-mA load.
Designed for noise-sensitive 5-V digital systems, it features center-pin VCC and GND configuration to minimize high-speed switching noise, and delivers 500-mA typical latch-up immunity at 125°C - critical for industrial control and instrumentation applications where transient robustness is required.
Key Specifications

Pinout & Package
74ACT11032DBRE4 is housed in a 16-pin Plastic Shrink Small-Outline Package (SSOP, DB), 5.3 mm × 6.2 mm body, 0.65 mm lead pitch, JEDEC MO-150 compliant, with gull-wing leads and moisture sensitivity level (MSL) 1 (unlimited floor life at ≤30°C/60% RH).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A (Gate 1 Input A) | First input of Gate 1; accepts TTL- or CMOS-level signals; referenced to common GND. |
| 2 | 1B (Gate 1 Input B) | Second input of Gate 1; electrically identical to Pin 1; dual-input OR function per gate. |
| 3 | 1Y (Gate 1 Output) | Active-high OR output; drives up to ±24 mA; rail-to-rail swing between GND and VCC. |
| 4 | 2A (Gate 2 Input A) | First input of Gate 2; independent signal path; no internal coupling to other gates. |
| 5 | 2B (Gate 2 Input B) | Second input of Gate 2; shares same logic family characteristics as Pins 1–3. |
| 6 | 2Y (Gate 2 Output) | Output of Gate 2; electrically isolated; supports concurrent operation with all other gates. |
| 7 | GND | Power ground reference for all four gates; center-pin placement reduces ground bounce. |
| 8 | 3Y (Gate 3 Output) | Output of Gate 3; positioned adjacent to GND to minimize output-to-ground loop inductance. |
| 9 | 3A (Gate 3 Input A) | First input of Gate 3; layout symmetry aids PCB routing in multi-gate logic clusters. |
| 10 | 3B (Gate 3 Input B) | Second input of Gate 3; matches timing and loading specs of Pins 1 and 2. |
| 11 | 4Y (Gate 4 Output) | Final OR output; routed near VCC pin to balance power distribution across die. |
| 12 | 4A (Gate 4 Input A) | First input of Gate 4; completes full quad-gate set; identical AC/DC behavior to others. |
| 13 | 4B (Gate 4 Input B) | Second input of Gate 4; fully decoupled; no shared internal nodes with other gates. |
| 14 | VCC | Positive supply rail; center-pin placement minimizes simultaneous switching noise (SSN) during high-frequency transitions. |
| 15 | NC | No connect - internally unconnected; must remain floating or tied to GND per design guidelines. |
| 16 | NC | No connect - unused pad; not bonded; no electrical function; leave unconnected. |

FAQ
What logic family does the 74ACT11032DBRE4 belong to, and how does it differ from standard 74HC or 74LS?
The 74ACT11032DBRE4 belongs to the Advanced CMOS TTL-compatible (ACT) family. Unlike 74HC, it accepts TTL input voltage thresholds (VIH = 2.0 V, VIL = 0.8 V) while delivering CMOS power efficiency and 24-mA output drive. Versus 74LS, it offers lower ICC (<40 µA vs. ~10 mA), rail-to-rail outputs, and superior noise immunity - making the 74ACT11032DBRE4 ideal for mixed-technology 5-V systems where both legacy TTL and modern CMOS coexist.
Is the 74ACT11032DBRE4 pin-compatible with other 16-pin quad 2-input OR gate variants like the 74ACT32 or 74ACT02?
No - the 74ACT11032DBRE4 uses a unique pinout optimized for noise reduction, with center-placed VCC (Pin 14) and GND (Pin 7), unlike the 74ACT32 (VCC at Pin 16, GND at Pin 8). The 74ACT02 is a dual-gate variant with different pin count and assignment. Therefore, the 74ACT11032DBRE4 is not a drop-in replacement for those parts; PCB layout must match its specific DB-package pin map to ensure correct power integrity and signal routing.
What is the maximum operating frequency supported by the 74ACT11032DBRE4 in a typical 5-V logic chain?
The 74ACT11032DBRE4 has a maximum propagation delay of 9 ns (tPHL/tPLH) under worst-case conditions (VCC = 4.5 V, TA = 85°C). This supports reliable operation in synchronous logic paths up to approximately 55 MHz (1 / (2 × 9 ns)). In combinatorial-only use (e.g., asynchronous alarm generation), the 74ACT11032DBRE4 remains functional beyond 100 MHz, limited only by board-level signal integrity - not the 74ACT11032DBRE4's intrinsic timing.
Does the 74ACT11032DBRE4 require external decoupling capacitors, and if so, what value and placement is recommended?
Yes - Texas Instruments recommends one 0.1-µF ceramic capacitor placed as close as possible between Pin 14 (VCC) and Pin 7 (GND), directly adjacent to the 74ACT11032DBRE4 body. This mitigates high-frequency switching noise due to the SSOP package's inductance and the device's 1.5 ns minimum transition time. For systems with multiple 74ACT11032DBRE4 units, add a bulk 4.7-µF tantalum capacitor per power rail segment.
Is the 74ACT11032DBRE4 suitable for use in automotive applications?
The 74ACT11032DBRE4 is not AEC-Q100 qualified and is not specified for automotive use. While it operates from –40°C to +85°C - overlapping with commercial automotive cabin environments - Texas Instruments explicitly states that non-designated parts like the 74ACT11032DBRE4 are not intended for automotive applications unless specifically rated per ISO/TS 16949. For automotive deployments, select TI's automotive-qualified logic families instead of the 74ACT11032DBRE4.
