74HC32DTR2G

Overview

The onsemi 74HC32DTR2G is a high-performance silicon-gate CMOS integrated circuit containing four independent 2-input OR gates. It operates within a DC supply voltage range of 2.0 V to 6.0 V and supports an operating temperature range from -55°C to +125°C. The device features low input current, high noise immunity, and output drive capability equivalent to 10 LSTTL loads. It is housed in a 14-lead TSSOP package with a maximum quiescent supply current of 40 µA at 6.0 V and 125°C.

Feature Summary

• Provides quad 2-input positive-OR logic functionality
• Compatible with Standard CMOS outputs and LSTTL outputs when pullup resistors are used
• Features high noise immunity characteristic of CMOS devices
• Includes protection circuitry against electrostatic discharge

Applications

• General-purpose digital logic circuits requiring OR gate functions
• Interfaces between CMOS, NMOS, and TTL logic families
• Battery-powered applications due to low power consumption

Procurement Notes

Verify the specific package suffix 'DT' corresponds to the TSSOP-14 form factor required for your PCB layout. Confirm that the RoHS-compliant and lead-free status meets your environmental compliance standards. Ensure the operating voltage range of 2.0 V to 6.0 V aligns with your system's power supply rails before finalizing procurement.

Selection Notes

Select this component when four independent 2-input OR gates are needed in a compact surface-mount package. It serves as a pin-compatible alternative to LS32 devices. Consider the extended temperature range (-55°C to +125°C) if operating in harsh environments. Verify that the 14-TSSOP footprint matches your design constraints compared to SOIC or DIP alternatives.

Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices manufactured by onsemi. It implements the standard JEDEC No. 7A requirements for quad 2-input OR gates. The device is functionally identical to the 74HC32 but packaged specifically in the TSSOP-14 configuration for space-constrained surface-mount applications.

Replacement Considerations

The datasheet lists the 74HC32DR2G (SOIC-14 package) as a related product offering the same logical functionality in a different physical footprint.
