SN74ALS244CN

Overview

The SN74ALS244CN is an octal buffer and line driver manufactured by Texas Instruments, belonging to the ALS logic series. It features eight non-inverting inputs and outputs with three-state capability, housed in a 20-pin DIP package. The device operates within a supply voltage range of 4.75 V to 5.25 V. Key electrical characteristics include a high-level output current of -15 mA and a low-level output current of 48 mA. Static current consumption is specified at 9 mA, while operating power supply current reaches 17 mA. The component supports a minimum operating temperature of 0°C and a maximum of +70°C.

Feature Summary

• Provides octal buffering and line driving functions with non-inverting signal paths
• Features three-state outputs for effective bus line management and isolation
• Utilizes Advanced Low-Power Schottky (ALS) technology for optimized performance

Applications

• Memory address drivers
• Clock drivers
• Bus-oriented architectures

Procurement Notes

Verify the specific suffix 'CN' against official Texas Instruments documentation to confirm the exact package type and temperature grade. Ensure compatibility with standard 5V logic systems given the ALS series requirements. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and current production status before procurement.

Selection Notes

Select this component when designing systems requiring octal buffering with three-state control in a through-hole DIP format. The ALS series offers a balance between speed and power consumption suitable for general-purpose digital applications. Confirm that the 5V supply voltage and operating temperature range align with the target system environment and interface requirements.

Part Context

This component is part of the SN74ALS244 family of octal buffers and line drivers. It shares functional similarities with other variants like the SN74ALS244DWR but differs in packaging and potentially thermal characteristics. The ALS series represents a specific generation of bipolar logic designed for improved performance over earlier LS standards while maintaining pin compatibility.
