SN74ALS244C-1N

Overview

The SN74ALS244C-1N is an octal buffer and line driver from the Texas Instruments 74ALS logic family, housed in a 20-pin DIP package. It features non-inverting outputs with three-state capability controlled by separate input and output enable lines. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical characteristics include a low-level output current of 24 mA and a high-level output current of -15 mA. It functions reliably across an operating temperature range of 0°C to +70°C.

Feature Summary

• Provides eight non-inverting buffer channels with independent control for inputs and outputs
• Features three-state outputs to facilitate bus-oriented systems and data isolation
• Delivers high drive capability suitable for driving heavy loads or transmission lines

Applications

• Bus-oriented memory and address drivers
• Clock drivers and buffer circuits
• Data acquisition systems requiring signal isolation

Procurement Notes

Verify the specific suffix 'C-1' against the manufacturer's latest documentation to confirm pinout and electrical specifications. Ensure the package type matches the required through-hole mounting configuration. Cross-reference the RoHS status and environmental compliance details with the official datasheet before finalizing procurement decisions.

Selection Notes

Select this component when designing systems that require high-speed buffering with significant drive strength. The ALS series offers a balance between speed and power consumption compared to standard TTL. Consider the three-state feature for managing multiple devices on a shared data bus without signal contention.

Part Context

This part belongs to the SN74ALS244 family of octal buffers. It serves as a digital logic interface component designed for general-purpose applications. The device is manufactured using advanced Schottky logic technology to ensure fast switching times while maintaining low power dissipation relative to older logic families.

Replacement Considerations

SN74ALS244CN is a direct equivalent offering identical functionality in a compatible package. SN74ALS244CDWR provides the same logical operations but utilizes a surface-mount SOIC package instead of through-hole DIP.
