SN74ALS2541N

Overview

The SN74ALS2541N is an octal buffer and line driver manufactured by Texas Instruments, belonging to the Advanced Low-power Schottky (ALS) logic family. It features non-inverting true outputs with three-state capability, housed in a 20-pin PDIP 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 6 mA, while operating supply current reaches 25 mA. The component supports through-hole mounting and functions reliably within an ambient temperature range of 0°C to +70°C.

Feature Summary

• Octal configuration providing eight independent non-inverting buffers or line drivers
• Three-state output design enabling effective bus-oriented architectures
• Advanced Low-power Schottky technology ensuring high-speed performance with reduced power dissipation

Applications

• Bus-oriented memory and address drivers
• Clock drivers and buffer circuits
• Control line drivers for system interconnects

Procurement Notes

Verify the specific suffix 'N' confirms the PDIP-20 through-hole package variant. Confirm RoHS compliance status as required by project specifications. Check manufacturer discontinuation notices, as ALS series components may have limited availability or end-of-life status. Ensure pinout compatibility with existing PCB footprints before procurement.

Selection Notes

Select this component when designing systems requiring octal buffering with three-state isolation on shared data buses. The ALS series offers a balance of speed and power efficiency suitable for TTL-compatible environments. Consider the 48 mA low-level sink capability for driving heavy loads. Verify that the 5V supply tolerance aligns with the target system's power regulation capabilities.

Part Context

This part belongs to the Texas Instruments SN74ALS series, which utilizes Advanced Low-power Schottky technology. This family improves upon standard LS logic by offering faster switching speeds and lower power consumption per gate. The SN74ALS2541 specifically addresses the need for multi-bit signal conditioning and isolation in digital logic designs.
