Product details
Overview
74HC58DB,112 from Nexperia (formerly Philips Semiconductors) is a dual AND-OR logic gate IC in SO16 package, implementing one 2-wide 3-input AND-OR section (1A–1F → 1Y) and one 2-wide 2-input AND-OR section (2A–2D → 2Y), with typical propagation delays of 11 ns (1Y) and 9 ns (2Y) at VCC = 5 V, CL = 15 pF, used in combinational logic synthesis for industrial control sequencers.
For engineers reviewing the 74HC58DB,112 datasheet, 74HC58DB,112 pinout, 74HC58DB,112 application, or 74HC58DB,112 equivalent, key selection criteria include verified dual-section AND-OR topology, SO16 mechanical compatibility, HC-family voltage-level compatibility (2.0–6.0 V), and documented propagation delay asymmetry between sections.
Technical Context
The 74HC58DB,112 integrates two independent AND-OR combinatorial blocks on a single Si-gate CMOS die: Section 1 performs (1A·1B·1C)+(1D·1E·1F); Section 2 performs (2A·2B)+(2C·2D). Both outputs are fully buffered push-pull, supporting standard TTL load drive (±4 mA).
It complies with JEDEC Std 7A and exhibits rail-to-rail input voltage tolerance (VI = GND to VCC), with input capacitance of 3.5 pF and power dissipation capacitance of 18 pF per gate - enabling predictable dynamic power estimation across 2.0–6.0 V supply range and −40 °C to +125 °C operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0 V to 6.0 V - supports mixed-voltage system interfacing without level shifters |
| tPHL/tPLH (1Y) | 11 ns typ. @ 5 V, 15 pF - defines maximum clock-to-output timing for first section in synchronous logic |
| tPHL/tPLH (2Y) | 9 ns typ. @ 5 V, 15 pF - enables faster response in second section for priority encoding paths |
| CI | 3.5 pF - limits capacitive loading on driving gates, critical for fan-out calculation |
| CPD | 18 pF per gate - enables accurate dynamic power modeling using PD = CPD × VCC² × fi |
| Operating Temp | −40 °C to +125 °C - qualified for under-hood automotive and industrial motor-control environments |
Pinout & Package
74HC58DB,112 is housed in a 16-pin small-outline (SO16) package with 1.27 mm pitch, body width 3.9 mm, and JEDEC MS-012AC outline compliance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 12, 13, 9, 10, 11 | 1A–1F inputs | Six inputs for first AND-OR section: three 2-input AND terms summed at 1Y |
| 2, 3, 4, 5 | 2A–2D inputs | Four inputs for second AND-OR section: two 2-input AND terms summed at 2Y |
| 6, 8 | 1Y, 2Y outputs | Active-high, fully buffered CMOS outputs capable of ±4 mA drive |
| 7 | GND | Logic ground reference; must be low-impedance connection to minimize switching noise |
| 14 | VCC | Positive supply; decoupling capacitor required within 10 mm of pin for stable operation |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual AND-OR logic applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT58DB,112 | TTL-compatible input thresholds (VIH = 2.0 V min), identical pinout and AC specs | Better interoperability with mixed 5 V TTL/CMOS systems where input noise margin is critical | Select when interfacing directly with 74LS/74ALS outputs without level translation |
| SN74HC58DR | SOIC-16 package, same logic function and DC/AC specs, Texas Instruments branding | No functional difference; TI's version has identical timing and drive but different traceability and lot documentation | Select when BOM requires TI-sourced components for qualification consistency |
Compared with 74HC58DB,112, the 74HCT58DB,112 offers improved noise immunity in TTL-mixed systems, while SN74HC58DR provides identical functionality with alternate supply-chain provenance - both require no PCB changes but differ in input threshold behavior and sourcing origin.

FAQ
What logic function does the 74HC58DB,112 implement?
The 74HC58DB,112 implements two independent AND-OR gates: Section 1 computes (1A·1B·1C)+(1D·1E·1F) at output 1Y; Section 2 computes (2A·2B)+(2C·2D) at output 2Y. This structure enables direct hardware realization of sum-of-products Boolean expressions without external gates, making the 74HC58DB,112 ideal for compact state-machine decoding and priority encoding tasks.
Is the 74HC58DB,112 pin compatible with older TTL devices?
Yes, the 74HC58DB,112 is pin compatible with low-power Schottky TTL (74LS58) and meets JEDEC Std 7A, allowing direct replacement in existing layouts. Its SO16 footprint matches legacy designs, and its output drive (±4 mA) interfaces cleanly with LS loads - confirming that the 74HC58DB,112 delivers true drop-in upgrade capability without PCB modification.
What is the maximum operating temperature for the 74HC58DB,112?
The 74HC58DB,112 is rated for operation from −40 °C to +125 °C, validated across the full range per manufacturer specifications. This extended temperature grade supports deployment in under-hood automotive modules and industrial motor drives where ambient temperatures exceed 85 °C - a key reliability advantage confirmed in the official Nexperia datasheet for the 74HC58DB,112.
Does the 74HC58DB,112 require external pull-up resistors on its inputs?
No, the 74HC58DB,112 has CMOS inputs with rail-to-rail voltage tolerance (VI = GND to VCC) and negligible input leakage (<1 µA), eliminating the need for external pull-ups. Inputs float to indeterminate states if left unconnected, so the 74HC58DB,112 must be used with driven or actively terminated inputs - a design requirement explicitly stated in the Philips/Nexperia application guidelines for the 74HC58DB,112.
How does the 74HC58DB,112 differ from the 74HC58N (DIP package)?
The 74HC58DB,112 and 74HC58N share identical logic function, DC/AC electrical specifications, and thermal ratings, differing only in package: SO16 surface-mount versus 16-pin PDIP through-hole. The 74HC58DB,112 offers smaller footprint, better high-frequency performance due to lower parasitic inductance, and compatibility with automated SMT assembly - making it the preferred choice for modern high-density designs using the 74HC58DB,112.
