TC74LCX374FT(EL)

Overview

The TC74LCX374FT(EL) is an octal D-type flip-flop with 3-state outputs manufactured by Toshiba Semiconductor and Storage. It belongs to the LCX series of low-voltage CMOS logic devices, designed for high-speed data storage applications. The component operates within a supply voltage range of 1.65V to 3.6V and features true output polarity. It is housed in a 20-pin TSSOP package with a 0.65mm pitch, suitable for surface-mount assembly. The device supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides eight independent D-type flip-flops with positive-edge triggering for parallel data capture
• Features three-state outputs to facilitate bus-oriented memory and clocked I/O designs
• Operates at low supply voltages ranging from 1.65V to 3.6V for power efficiency
• Compatible with standard 5V TTL input levels despite low-voltage operation

Applications

• Bus-oriented memory register implementations
• Clocked I/O buffers for data interface management
• Parallel-to-serial conversion circuits
• High-speed data latching in portable electronic devices

Procurement Notes

Verify the specific suffix (EL) against the manufacturer's current datasheet to confirm packaging details and compliance status. Ensure the ordering part number matches the required tape-and-reel specifications. Cross-reference the RoHS directive compliance and lead-free characteristics with the latest official documentation before procurement to avoid discrepancies.

Selection Notes

Select this component when designing systems requiring octal storage with low voltage operation between 1.65V and 3.6V. It is appropriate for applications needing compatibility with 5V logic inputs while maintaining low power consumption. Consider the TSSOP-20 package constraints for PCB layout and thermal management requirements in dense surface-mount designs.

Part Context

This device is part of Toshiba's LCX series, which focuses on low-voltage, high-speed CMOS logic. The LCX family bridges the gap between older LVC series and newer VCX series, offering optimized performance for modern portable electronics. It shares functional similarities with industry-standard 74LCX374 devices but utilizes Toshiba's specific manufacturing processes and packaging options.

Replacement Considerations

Direct pin-compatible substitutes include other manufacturers' 74LCX374 variants such as those from ON Semiconductor or NXP. Verify that replacement parts maintain the same 1.65V to 3.6V operating range and 3-state output characteristics. Ensure the alternative package matches the 20-TSSOP form factor for direct board replacement.
