TC74HC4050AFELF

Overview

The TC74HC4050AFELF is a hex non-inverting buffer manufactured by Toshiba Semiconductor and Storage using silicon gate C2MOS technology. It operates within a supply voltage range of 2.0 V to 6.0 V, with an operating temperature range of -40°C to +85°C. The device features a typical propagation delay of 9 ns at 5.0 V and a maximum quiescent current of 1.0 µA. Output drive capability is symmetrical, providing minimum currents of 6 mA for both high and low states. Input protection circuits allow logic-level conversion from voltages up to 15 V.

Feature Summary

• Non-inverting hex buffer configuration utilizing silicon gate C2MOS technology
• Input protection circuits enable logic-level conversion from high-level voltages up to 15 V
• Power-down protection provided on all inputs
• High noise immunity with balanced propagation delays

Applications

• Battery backup circuits where input voltage can be applied without biasing the IC by VCC
• Logic-level translation between different voltage domains
• Signal buffering in digital systems requiring high speed and low power dissipation

Procurement Notes

Verify that the specific ordering suffix corresponds to the SOP16 surface-mount package and reel packaging format. Confirm RoHS compliance status through official Toshiba documentation or authorized distributors before procurement. Ensure design accounts for absolute maximum ratings, particularly regarding input voltage limits relative to ground versus supply voltage.

Selection Notes

Select this component when a non-inverting buffer is required for signal conditioning. The TC74HC4050AF differs from the TC74HC4049AF, which provides an inverting function. Consider the wide input voltage tolerance if interfacing with higher voltage logic sources. Verify that the 2-stage internal circuit architecture meets the stability requirements for the specific application environment.

Part Context

This part belongs to the TC74HC40xx series of CMOS digital integrated circuits produced by Toshiba Electronic Devices & Storage Corporation. Commercial production for this family began in May 1986. The device is designed to achieve high-speed operation similar to equivalent LSTTL while maintaining standard CMOS low-power dissipation characteristics.

Replacement Considerations

The TC74HC4049AF is a related component within the same datasheet but functions as an inverting buffer. No other direct substitute part numbers are confirmed in the provided source material.
