TC74HC4050AP(F)

Overview

The TC74HC4050AP(F) is a hex non-inverting buffer and level converter fabricated with silicon gate C2MOS technology. It operates within a supply voltage range of 2.0 V to 6.0 V. The device features a typical propagation delay of 9 ns at 5.0 V and maintains a maximum quiescent current of 1.0 µA. It provides symmetrical output impedance with minimum currents of 6 mA for both high and low states. Input protection circuits allow logic-level conversion from voltages up to 15 V without biasing the IC.

Feature Summary

• Non-inverting hex buffer configuration with internal circuitry providing high noise immunity and stable outputs.
• Input protection circuits eliminate VCC-side diodes, enabling logic-level translation from high-level voltages up to 15 V to lower levels.
• Power-down protection is provided on all inputs, allowing input voltage application even when the IC is not biased by VCC.
• Balanced propagation delays and symmetrical output impedance ensure consistent signal integrity across operating conditions.

Applications

• Battery backup circuits requiring voltage level translation
• Interfaces between high-voltage logic sources and low-voltage CMOS systems
• General-purpose buffering in digital logic designs

Procurement Notes

Verify the specific ordering suffix (F) against the manufacturer's official documentation to confirm packaging details, as suffixes may indicate variations in tape-and-reel specifications or environmental compliance status. Ensure the procurement request explicitly references the full part number TC74HC4050AP(F) to distinguish it from other variants in the TC74HC4050 family.

Selection Notes

Select this component when a non-inverting buffer is required for translating signals from higher voltage domains (up to 15 V) to standard CMOS levels. It is suitable for applications demanding low power consumption alongside high-speed operation. Consider the DIP-16 package constraints and verify that the input voltage limits do not exceed the absolute maximum ratings under all expected operating conditions.

Part Context

This component belongs to the TC74HC4050 series of high-speed CMOS hex buffers manufactured by Toshiba Semiconductor and Storage. It is part of the HC logic family, designed to offer performance comparable to LSTTL while maintaining CMOS low-power characteristics. The series includes complementary inverting buffers like the TC74HC4049AP.

Replacement Considerations

The TC74HC4049AP serves as a functional substitute if an inverting buffer is acceptable instead of non-inverting. Other HC-series hex buffers from different manufacturers may be compatible if pinouts and electrical characteristics align, though specific verification of input protection and voltage tolerance is required.
