TC74LCX373FT(EL)

Overview

The TC74LCX373FT(EL) is an 8-bit transparent D-type latch manufactured by Toshiba Semiconductor and Storage. It belongs to the LCX logic series, designed for low-voltage CMOS applications with a supply voltage range of 1.65 V to 3.6 V. The device features high-speed performance with a propagation delay of 8.0 ns and provides strong drive capability with output currents of ±24 mA. It is housed in a compact VSSOP-20 surface-mount package, suitable for portable and battery-operated systems requiring efficient data storage and bus interfacing.

Feature Summary

• Transparent latch architecture allowing direct data passage when enabled
• High noise immunity and low power consumption characteristics
• Strong output drive capability for reliable signal transmission
• Compatible with standard CMOS logic input levels

Applications

• Data storage in portable electronic devices
• Bus driver interfaces for low-voltage systems
• Clocked memory modules in consumer electronics
• Signal buffering in communication equipment

Procurement Notes

Verify the specific ordering suffix (EL) against the manufacturer's current datasheet to confirm package dimensions and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the VSSOP-20 form factor. Cross-reference RoHS compliance status with the latest environmental declarations provided by Toshiba Semiconductor and Storage before finalizing procurement orders.

Selection Notes

Select this component when designing circuits that require 8-bit latching functionality within a strict low-voltage envelope. The LCX series offers superior speed compared to older LVX variants while maintaining lower power dissipation. Consider the VSSOP-20 package constraints regarding thermal management and soldering profiles during the layout phase to ensure reliable assembly and long-term operational stability.

Part Context

This part is a member of the Toshiba 74LCX family, which bridges the performance gap between standard CMOS and advanced low-voltage technologies. The LCX series is optimized for 1.8V and 3.3V systems, offering faster switching speeds than the LVX line. The TC74LCX373 specifically provides non-inverting outputs, making it distinct from inverting buffer counterparts within the same logical family structure.

Replacement Considerations

Direct substitutes include the 74LCX373FT(AE) from Toshiba, which shares identical electrical characteristics but may differ in packaging or reel specifications. Verify pinout compatibility and voltage tolerances before swapping components to prevent circuit malfunction.
