TC74AC244F(EL,F)

Overview

The TC74AC244F(EL,F) is a CMOS logic buffer and line driver manufactured by Toshiba Semiconductor and Storage. It belongs to the AC logic series and features four non-inverting input lines driving four output lines. The device operates within a supply voltage range of 2.0 V to 5.5 V, with a maximum propagation delay of 4.0 ns. It provides high drive capability with output currents of ±24 mA at both high and low states. Static current consumption is limited to 8 µA. The component supports surface-mount installation in a SOP package and functions reliably across an operating temperature range from -40 °C to +85 °C.

Feature Summary

• Provides four-channel non-inverting buffering for signal integrity maintenance
• Delivers high drive strength suitable for direct interface with loads
• Operates efficiently with minimal static power consumption

Applications

• Bus-oriented memory and address drivers
• Clock distribution buffers
• Driving capacitive or transmission-line loads

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and reel specifications. Ensure the requested part matches the exact alphanumeric designation to avoid discrepancies in pinout or electrical characteristics. Cross-reference the RoHS status and moisture sensitivity level requirements with your assembly process standards before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring moderate speed and high drive current within a wide voltage range. The AC series offers a balance between performance and power efficiency compared to older logic families. Consider the SOP package constraints and thermal dissipation capabilities during layout planning to ensure reliable operation under specified load conditions.

Part Context

This device is part of Toshiba's broader TC74AC family of CMOS logic integrated circuits. It serves as a specialized buffer solution within the company's portfolio of standard logic components. The product aligns with industry-standard pinouts and electrical definitions for octal bus drivers, facilitating integration into existing digital system architectures without requiring significant redesign.

Replacement Considerations

Consult official cross-reference lists for compatible alternatives. Verify that any substitute maintains identical pin configurations and electrical parameters to ensure functional compatibility.
