TC74LVX573FTEL

Overview

The TC74LVX573FTEL is an octal transparent latch manufactured by Toshiba Semiconductor and Storage. It features a 20-pin TSSOP package with a shrink pitch of 0.25 inches. The device operates within a voltage range supporting 3V systems, providing high-speed operation while maintaining low power dissipation typical of CMOS technology. Key electrical parameters include a maximum接通延迟时间 (turn-on delay) of 5.9 ns, with both high-level and low-level output currents rated at 4 mA. It contains eight independent non-inverting circuits. The component is designed for lead-free compliance and functions reliably across an operating temperature range from -40 °C to 85 °C.

Feature Summary

• Octal transparent latch configuration with non-inverting outputs
• High-speed CMOS technology ensuring stable operation in 3V systems
• Integrated input protection circuits against static discharge or transient excess voltage

Applications

• Low-voltage battery-operated systems
• Memory mapping applications requiring data latching
• I/O port expansion in embedded controllers

Procurement Notes

Verify the specific ordering suffix to confirm the tape and reel packaging format required for automated assembly processes. Ensure the procurement specification explicitly requests lead-free compliant units to match the documented manufacturing standard. Confirm that the supplier provides traceability documentation consistent with the manufacturer's quality standards for automotive or industrial grade components.

Selection Notes

Select this component when designing systems requiring octal data storage with high noise immunity and low power consumption. The 4 mA drive capability supports moderate capacitive loads up to 50 pF. Consider the 5.9 ns delay for timing-critical paths where propagation speed is essential but absolute highest performance is not required compared to VCX series devices.

Part Context

This part belongs to the TC74LVX series of low-voltage CMOS logic devices. It serves as a parallel-to-serial interface element or temporary data holder in digital circuits. The LVX series is characterized by its ability to operate at lower supply voltages than traditional HC series parts while offering improved switching speeds. It complements other LVX family members like the TC74LVX374 flip-flop for complex sequential logic designs.
