TC4001BF(EL,N,F)

Inverter Gates Overview

The TC4001BF(EL,N,F) is a CMOS digital integrated circuit containing four independent 2-input positive NOR gates. It operates within a DC supply voltage range of 3 V to 18 V and supports an operating temperature range from -40 °C to +85 °C. The device features buffered outputs that improve input/output transmission characteristics and minimize transmission time variation under increased load capacity. Key electrical parameters include a maximum propagation delay of 200 ns at 5 V, 100 ns at 10 V, and 80 ns at 15 V (with CL = 50 pF). Quiescent supply current typically ranges from 0.25 μA to 1.0 μA depending on the supply voltage.

Inverter Gates Feature Summary

• Contains four independent 2-input positive NOR logic gates
• Features buffered outputs for improved transmission characteristics
• Operates across a wide DC supply voltage range
• Supports standard surface-mount packaging

Inverter Gates Applications

• General-purpose digital logic circuits
• Signal processing applications requiring NOR logic functions
• Industrial control systems operating within specified temperature ranges

Inverter Gates Procurement Notes

Verify the specific package variant required, as the BF suffix indicates a surface-mount configuration (typically SOP or TSSOP). Confirm RoHS compliance status with the manufacturer representative prior to ordering. Ensure design accounts for absolute maximum ratings, particularly regarding power dissipation limits which vary by package type. Review the Toshiba Semiconductor Reliability Handbook for derating concepts and handling precautions before integration.

Inverter Gates Selection Notes

Select this component when a quad 2-input NOR gate is required in a CMOS process. Consider the buffered output structure if minimizing transmission time variation under varying load conditions is critical. Verify that the application environment stays within the -40 °C to +85 °C operating temperature range. Ensure unused inputs are tied to either VDD or VSS to maintain normal operation and prevent undefined states.

Inverter Gates Part Context

This part belongs to the TC4001B series, which includes variants such as TC4001BP (DIP) and TC4001BFT (TSSOP). All variants share the same internal quad 2-input NOR gate architecture and electrical specifications. The primary distinction lies in the physical package and pin assignment dimensions. The BF suffix specifically denotes the surface-mount package option available for this logic family.
