TC74VHC4040FT(EL,M)

Overview

The TC74VHC4040FT(EL,M) is a 12-stage ripple carry binary counter fabricated using Toshiba's silicon gate C2MOS technology. It operates within a supply voltage range of 2.0 V to 5.5 V and supports an operating temperature range from -40°C to +85°C. The device provides all divided output stages, achieving a maximum clock frequency of 125 MHz at 5.0 V with a 50 pF load. Quiescent supply current is limited to 4.0 μA at 5.5 V and 25°C.

Feature Summary

• Provides high-speed operation comparable to Bipolar Schottky TTL while maintaining CMOS low power dissipation.
• Features input protection circuits allowing 0 to 5.5 V application to input pins regardless of supply voltage.
• Ensures balanced propagation delays between low-to-high and high-to-low transitions.

Applications

• General electronics applications including computers and personal equipment
• Industrial robots and measuring equipment
• Home electronics appliances

Procurement Notes

Verify the specific package type (TSSOP-16) and suffix designations against official Toshiba documentation before procurement. Confirm RoHS compliance status directly with the manufacturer or authorized distributors. Ensure that ordering specifications match the required electrical characteristics and environmental ratings for the intended application environment.

Selection Notes

Select this component when a 12-stage binary counter is required for general-purpose digital logic applications. It is suitable for interfacing 5 V systems with 3 V systems due to its wide input voltage tolerance. Consider the device for designs requiring low noise immunity and power-down protection on all inputs.

Part Context

This part belongs to the TC74VHC4040 series, which includes variants such as TC74VHC4040F, TC74VHC4040FN, and TC74VHC4040FK. These devices are pin and function compatible with the standard 74HC4040 logic family. The series utilizes advanced high-speed CMOS technology to deliver performance similar to equivalent Bipolar Schottky TTL circuits.

Replacement Considerations

The TC74VHC4040FT(EL,M) is pin and function compatible with the 74HC4040. Verify that any substitute component matches the 2.0 V to 5.5 V operating voltage range and the -40°C to +85°C temperature specifications to ensure proper system integration.
