74LCX374WMX

Overview

The onsemi 74LCX374WMX is an octal D-type flip-flop featuring three-state outputs, designed for low-voltage CMOS applications. It operates within a supply voltage range of 2V to 3.6V and supports clock frequencies up to 150MHz. The device exhibits a maximum propagation delay of 8.5ns at 3.3V with a 50pF load. It utilizes a 20-pin SSOP package (0.209 inch width) and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Octal D-type flip-flop architecture with eight independent data storage elements
• Three-state outputs enabling direct connection to bus-organized systems without interface components
• Low power consumption with static current draw of 10µA
• CMOS compatible input structure ensuring high noise immunity

Applications

• Buffer registers in digital signal processing systems
• I/O ports for microcontroller interfaces

Procurement Notes

Verify the specific suffix 'WMX' against official datasheets to confirm the tape-and-reel packaging format. Ensure the component meets RoHS3 compliance requirements if mandated by project specifications. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before procurement.

Selection Notes

Select this component when low voltage operation between 2V and 3.6V is required alongside high-speed performance up to 150MHz. The SSOP package is suitable for space-constrained surface-mount designs. Consider the 8.5ns propagation delay for timing-critical paths and verify that the three-state output drive capability matches the load requirements of the destination circuitry.
