Key Features
- Schmitt-trigger inputs with hysteresis provide noise immunity for reliable NAND logic operation on slow-rise or noisy input signals
- Quad 2-input configuration with four independent NAND gates maximizes logic density for compact TTL-based circuit designs
- Standard 14-pin DIP (R-PDIP-T14) package in the TTL/H/L family ensures compatibility with legacy and new 5V digital logic systems
Applications
The SN74132N3 is used in digital logic systems where input signals have slow edge rates, noise, or ringing that could cause false triggering in standard NAND gates. The Schmitt-trigger inputs allow it to function as a signal conditioner, clock generator, or debounce circuit in microcontroller interfaces and industrial control systems. It is also commonly used in astable and monostable oscillator configurations where reliable switching from noisy or analog-threshold input signals is required.

Frequently Asked Questions
What makes the SN74132N3 different from a standard NAND gate?
The SN74132N3 uses Schmitt-trigger inputs with built-in hysteresis, unlike standard NAND gates. This hysteresis ensures clean, noise-free switching even when input signals have slow rise/fall times, ringing, or electrical noise, preventing multiple output transitions from a single input edge.
How many NAND gates are in the SN74132N3?
The SN74132N3 contains four independent 2-input positive-NAND gates with Schmitt-trigger inputs. Each gate operates independently, allowing use of multiple logic functions within a single 14-pin DIP package for compact digital circuit designs.
What is the operating temperature range of the SN74132N3?
The SN74132N3 is rated for operation from 0°C to 70°C, covering standard commercial temperature requirements for use in indoor electronic systems, laboratory instruments, and consumer digital equipment within normal operating environments.
What package does the SN74132N3 come in?
The SN74132N3 is housed in a 14-pin PDIP (R-PDIP-T14) plastic/epoxy through-hole package with a 0.3-inch row spacing. This DIP format supports breadboard prototyping, IC socket mounting, and through-hole PCB assembly in TTL logic circuit designs.
Is the SN74132N3 RoHS compliant?
No, the SN74132N3 has a Pbfree Code of No, meaning it uses standard tin-lead solder termination and is not RoHS compliant. It is intended for applications where lead-free compliance is not required, such as legacy industrial equipment, repair, or non-regulated markets.
