TC7W74FU,LF

Overview

The TC7W74FU,LF is a single D-type flip-flop from Toshiba’s TC7W series, housed in an 8-SSOP surface-mount package. It operates on a supply voltage range of 2V to 6V and supports a maximum clock frequency of 170 MHz. The device features differential outputs with specified high-level output current of -8 mA and low-level output current of 8 mA. Propagation delay is rated at 15.4 ns. It includes preset and clear functions, accepts single-ended inputs, and provides both inverting and non-inverting polarities. The component is designed for industrial temperatures ranging from -40°C to +85°C.

Feature Summary

• Integrates a single D-type flip-flop with preset and clear functionality within a compact 8-pin SSOP package.
• Supports high-speed operation with a maximum clock frequency of 170 MHz and low propagation delay.
• Features differential outputs capable of sourcing and sinking significant drive currents for reliable signal transmission.

Applications

• High-speed digital data storage and transfer circuits
• Parallel-to-serial and serial-to-parallel data conversion interfaces
• Timing control and pulse synchronization logic

Procurement Notes

Verify the complete part number including the suffix to ensure correct packaging and compliance status. Confirm that the specific ordering code matches the required tape-and-reel or cut-tape format for automated assembly processes. Cross-reference the manufacturer's latest documentation to validate RoHS3 compliance and environmental declarations before finalizing procurement orders.

Selection Notes

Select this component when a single-bit storage element with independent preset and clear controls is required in space-constrained designs. Ensure the system voltage remains within the 2V to 6V operating range. Consider the 170 MHz maximum frequency limit for timing-critical applications. Verify that the 8-SSOP footprint aligns with the PCB layout constraints and thermal requirements of the target environment.

Part Context

This device belongs to the TC7W family of L-MOS logic ICs, which are characterized by high speed and low power consumption. It serves as a fundamental building block for sequential logic circuits. Compared to dual-flip-flop variants, this single-element configuration offers reduced pin count and simplified routing for minimalistic digital designs requiring precise edge-triggered data handling.

Replacement Considerations

The TC7W74FK,LF is a confirmed substitute offering identical logical function and pinout compatibility. Both parts share the same 8-SSOP package and electrical specifications, allowing for direct interchangeability in existing designs without circuit modification.
