TC74LCX16373(EL,F)

Overview

The TC74LCX16373(EL,F) is a 16-bit D-type flip-flop with 3-state outputs manufactured by Toshiba Semiconductor and Storage. It belongs to the LCX logic family, designed for low-voltage CMOS applications. The device features true outputs and is housed in a 54-pin SSOP package. Key electrical characteristics include a maximum output skew of 1.5 ns and a maximum VOLP of 0.8 V at VCC = 3.3 V and TA = 25 °C. It supports an operating temperature range up to 85 °C and has a load capacitance specification of 50 pF.

Feature Summary

• Provides 16-bit data storage with 3-state output control for bus sharing applications
• Operates within a low voltage supply range compatible with LV/LV-A/LVX/H series standards
• Features high-speed performance with specified maximum output skew limits

Applications

• High-density data buffering in digital systems
• Bus driver applications requiring 3-state isolation
• Portable equipment utilizing low-voltage power supplies

Procurement Notes

Verify the specific suffix (EL or F) against the manufacturer's current datasheet to confirm pinout compatibility and packaging dimensions. Ensure the component meets RoHS requirements if applicable, as older revisions may differ. Confirm the operating temperature range matches system specifications before procurement.

Selection Notes

Select this component when a 16-bit wide data path with tri-state capability is required. It is suitable for systems transitioning from higher voltage logic families to 3.3V environments. Consider the 54-pin SSOP package constraints for PCB layout and thermal management during selection.

Part Context

This part is part of Toshiba's LCX series, which bridges the gap between legacy LVC and newer LVX technologies. It offers improved speed and lower power consumption compared to older HC/HCT families while maintaining pin compatibility with standard 16-bit latch designs. The series is widely used in consumer electronics and industrial control modules.

Replacement Considerations

Direct substitutes include other 16-bit 3-state latches from manufacturers like ON Semiconductor or NXP, provided they match the 3.3V supply and SSOP-54 package. Verify input/output voltage levels and propagation delays to ensure functional equivalence in the target circuit.
