TC74LCX16245ELF

Overview

The TC74LCX16245ELF is a low-voltage CMOS bus transceiver from Toshiba's 74LCX series, housed in a 48-TSSOP package. It features two non-inverting elements, each handling eight bits, providing a total of 16-bit bidirectional data transmission capability. The device supports a supply voltage range of 2.0V to 3.6V and operates within a temperature range of -40°C to +85°C. Key electrical characteristics include five-volt tolerant inputs and outputs, which allow safe interfacing between low-voltage logic and legacy 5V systems without level shifting components.

Feature Summary

• Provides bidirectional data transfer via two independent 8-bit channels
• Features five-volt tolerant inputs and outputs for mixed-voltage system compatibility
• Operates with low supply voltage ranging from 2.0V to 3.6V
• Utilizes push-pull output structure for improved switching speed and noise immunity

Applications

• Memory bus architectures requiring 16-bit wide data paths
• Mixed-voltage interface circuits connecting 3.3V logic to 5V peripherals
• High-density digital signal processing systems
• Portable electronic devices utilizing low-power CMOS logic

Procurement Notes

Verify the specific ordering suffix matches the required tape-and-reel configuration, as packaging options may vary by distributor. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the TSSOP-48 footprint aligns with your PCB design constraints. Cross-reference the datasheet revision date to ensure all electrical specifications remain current for your application requirements.

Selection Notes

Select this component when a 16-bit bidirectional interface is required between low-voltage domains and 5V-tolerant networks. The 74LCX series offers superior performance compared to older HC/HCT families at lower voltages. Consider the 48-pin TSSOP package for space-constrained designs requiring high pin density. Evaluate power consumption requirements against the low static current characteristics typical of CMOS technology.

Part Context

This part belongs to Toshiba's 74LCX family of low-voltage CMOS logic devices, designed for high-speed applications with reduced power consumption. The LCX series bridges the gap between standard 5V logic and modern 3.3V or lower voltage systems. Bus transceivers in this family are essential for managing data flow in complex digital systems where voltage level mismatches exist between different subsystems.

Replacement Considerations

Check for direct equivalents such as the TC74LCX16245 without the ELF suffix if reel packaging is not mandatory. Verify functional compatibility with other 74LCX16245 variants from different manufacturers, ensuring pinout and electrical parameters match exactly before substitution.
