CD74HC374E-NG

Overview

The CD74HC374E-NG is an octal D-type flip-flop manufactured by Texas Instruments, belonging to the HC logic family. It features eight non-inverting outputs with three-state control, housed in a 20-pin PDIP package. The device operates within a supply voltage range of 2 V to 6 V and supports through-hole mounting. It exhibits a propagation delay of 230 ns at 2 V and provides output drive currents of ±7.8 mA. The component functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Contains eight independent D-type flip-flops for parallel data storage
• Provides three-state outputs controlled by a dedicated OE pin
• Features positive-edge triggering for clock synchronization

Applications

• Registering digital data in microprocessor systems
• Buffering memory address lines
• Driving high-capacitance loads in bus architectures

Procurement Notes

Verify the specific suffix 'NG' against official manufacturer documentation to confirm exact packaging or material specifications. Ensure compatibility with standard 20-pin DIP footprints during PCB layout. Confirm RoHS compliance status directly with the supplier prior to procurement.

Selection Notes

Select this component when requiring an octal register with tri-state capability in a through-hole format. The HC series offers balanced speed and power consumption suitable for general-purpose logic applications. Verify that the system voltage remains within the 2 V to 6 V operational limits.

Part Context

This part belongs to the SN74HC374 family of octal D-type flip-flops. It shares functional similarities with other HC-series devices but is distinguished by its specific PDIP-20 packaging and through-hole installation requirements. It serves as a standard solution for parallel data retention in legacy and industrial electronic designs.

Replacement Considerations

SN74HC374N is a documented parameter-equivalent alternative from Texas Instruments.
