Overview
The SN74ALS244BN3 is an octal buffer and line driver manufactured by Texas Instruments, belonging to the Advanced Low-power Schottky (ALS) logic family. It features eight non-inverting buffers with three-state outputs controlled by two independent output enable inputs. The device operates within a supply voltage range of 4.75 V to 5.25 V. Key electrical characteristics include a low-level output current of 48 mA and a high-level output current of -15 mA. It functions reliably across an operating temperature range from 0°C to +70°C and is housed in a standard SOIC-20 package.
Feature Summary
- Provides eight non-inverting buffered channels for signal transmission
- Features three-state outputs allowing direct connection to bus systems
- Utilizes Advanced Low-power Schottky technology for optimized speed and power consumption
Applications
- Memory address drivers
- Clock drivers
- Bus-oriented transmissions
Procurement Notes
Verify the specific suffix 'N3' against official Texas Instruments documentation to confirm pinout compatibility and manufacturing lot details. Ensure the component meets the required ALS logic specifications and SOIC-20 package dimensions before integration into the design.
Selection Notes
Select this component when designing systems requiring octal buffering with three-state capability under standard 5V logic conditions. The ALS series offers a balance of propagation delay and power dissipation suitable for general-purpose digital applications where moderate speed is sufficient.
Part Context
This part belongs to the SN74ALS244 family of octal buffers. It shares functional similarities with other 74-series drivers but is distinguished by its specific ALS performance metrics and packaging. It serves as a critical interface component for managing data flow between microprocessors and peripheral devices.
Replacement Considerations
Compatible substitutes include the SN74ALS244DWR or SN74ALS244N, provided they match the SOIC-20 or DIP-20 package requirements and maintain identical electrical characteristics for the ALS logic family.
