Overview
The onsemi 74HC132DR2G is a high-performance silicon-gate CMOS quad 2-input NAND gate with Schmitt-trigger inputs. It operates within a supply voltage range of 2.0 V to 6.0 V and supports an operating temperature from -55°C to +125°C. The device features a maximum propagation delay of 21 ns at 6.0 V, output drive capability of 10 LSTTL loads, and low input current of 1.0 µA. Packaged in SOIC-14 (Case 751A), it provides ESD protection of 2000 V (HBM) and 200 V (Machine Model).
Feature Summary
- Schmitt-trigger inputs enhance noise immunity and square up slowly changing waveforms.
- Outputs directly interface to CMOS, NMOS, and TTL logic families.
- High noise immunity characteristic of CMOS devices.
- Compatible with standard CMOS outputs and LSTTL outputs when pull-up resistors are used.
Applications
- Squaring up slowly changing waveforms.
- Enhancing noise immunity in digital circuits.
- General-purpose logic applications requiring Schmitt-trigger functionality.
Procurement Notes
Verify the package suffix 'D' corresponds to the SOIC-14 form factor as specified in the datasheet. Confirm RoHS compliance and Pb-Free status for environmental requirements. Ensure the ordering quantity aligns with the standard tape and reel shipping configuration of 2500 units per reel.
Selection Notes
Select this component when Schmitt-trigger action is required for noisy signals or slow rise/fall times. It serves as a direct pinout-compatible replacement for LS132 devices. Consider the wide operating voltage range and extended temperature specifications for industrial environments.
Part Context
This part belongs to the 74HC series of high-speed CMOS logic devices manufactured by onsemi. It is functionally identical to the LS132 in terms of pinout but offers superior performance characteristics typical of CMOS technology, including lower power consumption and higher noise margins compared to older bipolar technologies.
Replacement Considerations
The datasheet notes that the 74HC132 is identical in pinout to the LS132. Designers replacing legacy LS132 components should verify that the new CMOS input thresholds and drive capabilities are compatible with the existing circuit design.
FAQ
How does the Schmitt-trigger feature benefit signal integrity?
The Schmitt-trigger inputs provide hysteresis, which enhances noise immunity and allows slowly changing input signals to be transformed into sharply defined, jitter-free output signals.
What is the ESD withstand capability of this device?
The device offers robust ESD protection, withstanding 2000 V via the Human Body Model (HBM) and 200 V via the Machine Model (MM).
