TC74VCX574FTEL

Overview

The TC74VCX574FTEL is a single-element, 8-bit D-type flip-flop manufactured by Toshiba Semiconductor and Storage. It operates within a supply voltage range of 1.2V to 3.6V and features positive-edge triggering with tri-state, non-inverting outputs. The component supports a maximum clock frequency of 250 MHz and delivers output currents of 24mA for both high and low states. Propagation delay is specified at 4.2ns under conditions of 3.3V supply and 30pF load capacitance. Static current consumption is limited to 20µA, while input capacitance remains at 6pF. The device is housed in a 20-TSSOP package with a width of 4.40mm and functions reliably across an operating temperature range of -40°C to 85°C.

Feature Summary

• Positive-edge triggered D-type configuration providing reliable data capture on clock transitions
• Tri-state output capability allowing bus line isolation and system flexibility
• Low voltage operation optimized for 1.5V, 1.8V, 2.5V, and 3.3V system environments
• High-speed performance supporting clock frequencies up to 250 MHz

Applications

• Data storage circuits requiring 8-bit parallel registration
• Bus interface systems utilizing tri-state buffering
• Level shifting applications between different voltage domains
• Digital signal processing pipelines needing fast propagation delays

Procurement Notes

Verify the specific ordering suffix to ensure correct packaging format, as variations exist between tape-and-reel and cut-tape options. Confirm that the component status is acceptable for your design lifecycle, noting it may be marked as not recommended for new designs. Cross-reference pinout compatibility if replacing existing components in established hardware layouts. Ensure supply chain sources provide authentic Toshiba Semiconductor and Storage products to avoid counterfeit risks.

Selection Notes

Select this component when designing low-voltage logic systems requiring high-speed data latching capabilities. The wide supply voltage range accommodates various modern digital standards without additional level shifters. Consider the 20-TSSOP package dimensions for PCB layout constraints. Evaluate the 24mA drive strength against downstream load requirements to ensure signal integrity. Verify thermal management needs given the operating temperature range and static power characteristics.
