TC74VCX244FTEL

Overview

The TC74VCX244FTEL is a low-voltage octal bus buffer manufactured by Toshiba Semiconductor and Storage. It operates within a supply voltage range of 1.2V to 3.6V and features 3.6V tolerant inputs and outputs. The device contains two non-inverting buffers, each with four bits, housed in a 20-TSSOP package. It provides high-speed operation while maintaining CMOS low power dissipation. The component supports surface mount installation and functions across an operating temperature range of -40°C to 85°C.

Feature Summary

• Provides 3.6V tolerant inputs and outputs for mixed-voltage system interfacing
• Operates at high speeds while maintaining low power consumption
• Includes protection circuits against static discharge on all inputs

Applications

• 1.5V, 1.8V, 2.5V, or 3.3V system applications
• Mixed-voltage bus buffering
• Low voltage data transmission lines

Procurement Notes

Verify the specific ordering suffix to confirm the exact packaging type required for your assembly process. Confirm RoHS compliance status and moisture sensitivity level before integration. Check current availability as this part may be subject to order fulfillment constraints. Ensure the 20-TSSOP footprint matches your PCB design requirements.

Selection Notes

Select this component when designing systems requiring low-voltage operation between 1.2V and 3.6V. It is suitable for applications needing 3.6V tolerance on both input and output pins. Consider the 20-TSSOP package size and the specific pinout configuration for board layout. Verify that the high-speed performance aligns with your signal integrity requirements.

Part Context

This part belongs to the TC74VCX series of low-voltage CMOS logic devices from Toshiba. The series is designed for use in portable and battery-operated equipment due to its low power characteristics. The 244 designation indicates an octal buffer configuration with three-state outputs, distinct from other logic families like ACT or LVC which may have different voltage tolerances or drive strengths.

Replacement Considerations

The Nexperia 74LVC244APW,118 is listed as a direct substitute. Verify pin compatibility and electrical specifications before substitution.
