74HC32DR2G

Overview

The onsemi 74HC32DR2G is a high-performance silicon-gate CMOS quad 2-input OR gate. It operates within a supply voltage range of 2.0 to 6.0 V and supports an operating temperature from -55°C to +125°C. The device provides an output drive capability equivalent to 10 LSTTL loads and features low input current of 1.0 nA. Propagation delay ranges from 13 ns at 6.0 V to 75 ns at 2.0 V with a 50 pF load. It is housed in a SOIC-14 package.

Feature Summary

• Outputs directly interface to CMOS, NMOS, and TTL logic families
• High noise immunity characteristic of CMOS devices
• ESD protection performance exceeding 2000 V for Human Body Model and 200 V for Machine Model
• Compliant with JEDEC Standard No. 7A requirements

Applications

• Digital logic circuits requiring OR functionality
• Signal routing and selection systems
• General-purpose logic applications compatible with standard CMOS outputs

Procurement Notes

Verify the specific ordering suffix 'DR2G' corresponds to the SOIC-14 package type and tape & reel shipping configuration. Confirm that the component meets Pb-Free specifications as indicated by the marking diagram. Ensure compatibility with the required operating voltage and temperature ranges for the target application environment before finalizing procurement.

Selection Notes

Select this component when a quad 2-input OR gate is required with high-speed CMOS performance. It serves as a pin-compatible alternative to LS32 devices while offering lower power consumption. Consider the propagation delay variations across the 2.0 V to 6.0 V supply range and the wide operating temperature span for system design integration.

Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices manufactured by onsemi. The 74HC32 implements the standard quad 2-input OR function. It is designed to be compatible with the pinout of the older LS32 TTL device, facilitating upgrades or replacements in existing designs while benefiting from CMOS characteristics such as low static power dissipation.

Replacement Considerations

The datasheet notes the device is identical in pinout to the LS32.
