TC4050BF(EL,N,F)

Overview

The TC4050BF(EL,N,F) is a CMOS logic integrated circuit manufactured by Toshiba Semiconductor and Storage. It functions as a non-inverting buffer containing six independent channels within a single package. The device utilizes a 16-pin Small Outline Package (SOP) with a rectangular plastic/epoxy body. It operates on a supply voltage ranging up to 18 V and supports an industrial temperature range from -40 °C to +85 °C. Key electrical specifications include a propagation delay of 130 ns and a maximum supply voltage of 18 V.

Feature Summary

• Provides six independent non-inverting buffer channels for signal conditioning
• Operates reliably across a wide industrial temperature range
• Compatible with standard CMOS logic families

Applications

• General-purpose digital signal buffering
• Level shifting in CMOS logic circuits
• Signal isolation in data transmission lines

Procurement Notes

Verify the specific suffix variant required, such as EL, N, or F, as these denote distinct packaging or reel configurations. Confirm that the 16-SOP footprint matches the target PCB design. Ensure the component meets RoHS compliance requirements if mandated by the end product regulations. Cross-reference the manufacturer's latest datasheet to confirm pinout compatibility before finalizing procurement orders.

Selection Notes

Select this component when a high-density solution for multiple non-inverting buffers is required in a compact surface-mount form factor. It is suitable for designs needing operation at supply voltages up to 18 V. Consider the 130 ns propagation delay when evaluating timing constraints for high-speed applications. Verify that the 16-pin SOP package dimensions fit within the available board space constraints.

Part Context

This part belongs to the 4000 series of CMOS logic devices, a long-standing family known for wide voltage operation. The TC4050BF variant specifically integrates six buffers into one chip, reducing component count compared to single-gate alternatives. It serves as a fundamental building block for digital logic systems requiring signal amplification without inversion.

Replacement Considerations

Direct substitutes may include other 4000-series hex non-inverting buffers from different manufacturers, provided they share the same 16-pin SOP package and electrical characteristics. Verify pin-to-pin compatibility and ensure the alternative device supports the required 18 V maximum supply voltage.
