TC74VCX16841(EL,F)

Overview

The TC74VCX16841(EL,F) is a D-type latch integrated circuit manufactured by Toshiba Semiconductor and Storage. It features a 20-bit configuration housed in a 56-pin TSSOP package. The device operates within a supply voltage range of 1.8V to 3.6V and supports an operating temperature range from -40°C to 85°C. It provides high-current outputs with drive capabilities of 6mA for both high and low states. The internal circuit architecture is configured as two independent 10:10 circuits, facilitating parallel data storage applications in digital systems.

Feature Summary

• Provides 20-bit D-type latching functionality for parallel data retention
• Supports dual independent 10:10 circuit configurations for flexible system design
• Delivers high-output current drive capability of 6mA in both logic states

Applications

• Parallel data bus interfacing and buffering
• Digital signal processing systems requiring temporary data storage
• Microcontroller peripheral expansion for I/O management

Procurement Notes

Verify the specific ordering suffix (EL,F) against the manufacturer's official documentation to ensure correct packaging and compliance specifications. Confirm that the component status aligns with project requirements, as availability may vary. Cross-reference the pinout and electrical characteristics with the latest datasheet to guarantee compatibility with existing board designs and regulatory standards.

Selection Notes

Select this component when a 20-bit latch solution is required within the 1.8V to 3.6V voltage domain. The 56-TSSOP package offers a compact footprint suitable for space-constrained designs. Ensure the application demands the specified 6mA output drive strength and operates within the -40°C to 85°C temperature range. Consider the obsolete status if long-term supply continuity is a critical constraint.

Part Context

This part belongs to the 74VCX series of advanced CMOS logic devices designed for low-voltage operation. The series emphasizes high speed and low power consumption, making it suitable for modern portable and battery-operated electronics. Toshiba utilizes this platform to provide reliable logic functions that interface seamlessly between different voltage domains in complex digital architectures.
