Overview
The onsemi 74HC132DTR2G is a Quad 2-Input NAND Gate with Schmitt-Trigger Inputs, manufactured using High-Performance Silicon-Gate CMOS technology. It operates within a DC supply voltage range of 2.0 to 6.0 V and supports an operating temperature from -55°C to +125°C. The device features a TSSOP-14 package and provides an output drive capability of 10 LSTTL loads. Key electrical characteristics include a maximum propagation delay of 21 ns at 6.0 V with a 50 pF load, low input leakage current of 1.0 µA, and high noise immunity.
Feature Summary
- Schmitt-trigger inputs convert slowly changing waveforms into clean, defined output signals.
- Outputs directly interface with CMOS, NMOS, and TTL logic families.
- High noise immunity characteristic of CMOS devices enhances signal integrity.
- Inputs are compatible with standard CMOS outputs and LSTTL outputs when pull-up resistors are used.
Applications
- Squaring up slowly changing waveforms for digital processing.
- Enhancing noise immunity in digital circuits.
- General-purpose logic gating in industrial and consumer electronics.
Procurement Notes
Verify the specific suffix 'DTR2G' corresponds to the TSSOP-14 package and tape & reel shipping configuration. Confirm RoHS compliance status as indicated by the 'G' suffix. Check for any product change notices or obsolescence announcements from onsemi prior to finalizing procurement plans.
Selection Notes
Select this component when Schmitt-trigger action is required to eliminate noise on slow-rising input signals. Ensure the application voltage remains within the 2.0 V to 6.0 V range. Consider the TSSOP-14 package constraints for PCB layout if space is limited compared to SOIC-14 alternatives.
Part Context
This part belongs to the 74HC series of high-speed CMOS logic gates. It is functionally pin-compatible with LS132 devices but offers lower power consumption and higher speed performance typical of HC technology. The device contains four independent 2-input NAND gates with Schmitt triggers on each input.
Replacement Considerations
Public confirmed substitute part numbers: MC74HC132ADTR2G (onsemi), SN74HC132DR (Texas Instruments). Verify package compatibility and operating temperature ranges before substitution.
FAQ
What is the primary benefit of the Schmitt-trigger inputs?
The Schmitt-trigger inputs provide hysteresis, which squares up slowly changing waveforms and eliminates output jitter caused by noise near the switching threshold.
How does the 74HC132DTR2G interface with LSTTL outputs?
While inputs are natively compatible with standard CMOS outputs, they can interface with LSTTL outputs by adding pull-up resistors to the inputs.
