Overview
The SN74ALS1244A-1N is an octal buffer and line driver manufactured by Texas Instruments, belonging to the Advanced Low-power Schottky (ALS) logic family. It features three-state outputs for bus-oriented applications. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a propagation delay of 10 ns. It is housed in a 20-pin PDIP package and functions within a temperature range of 0°C to +70°C.
Feature Summary
- Octal buffering with three-state output capability
- Advanced Low-power Schottky (ALS) technology
- Bus-oriented design for system flexibility
Applications
- Bus-oriented memory and data register systems
- Clock drivers
- Buffering of I/O circuits
Procurement Notes
Verify the specific suffix '1N' against the manufacturer's current datasheet to confirm the package type and pinout configuration. Ensure the component meets the required operating temperature range and voltage specifications for the target application environment before finalizing procurement.
Selection Notes
Select this component when high-speed buffering with low power consumption is required in ALS-compatible designs. The three-state outputs allow direct connection to data buses without additional gating logic. Verify that the input levels are compatible with the driving circuitry, typically TTL or CMOS standards.
Part Context
This part belongs to the SN74ALS series of logic integrated circuits from Texas Instruments. The ALS family offers improved speed and power dissipation characteristics compared to standard LS logic. The SN74ALS1244A variant specifically provides octal buffering functionality suitable for digital system interconnects.
Replacement Considerations
Compatible substitutes include other octal buffers with three-state outputs from the ALS family, such as the SN74ALS1241. Verify pin compatibility and electrical parameters before substitution.
