DM74ALS541WM

Overview

The DM74ALS541WM is an octal buffer and line driver manufactured by onsemi, utilizing the Advanced oxide-isolated ion-implanted Schottky TTL process. It features a data flow-thru pinout with inputs and outputs on opposite sides of the package to enhance circuit board layout. The device includes 3-STATE outputs controlled by a 2-input NOR gate (G1/G2). Recommended operating conditions specify a supply voltage range of 4.5V to 5.5V and an operating temperature of 0°C to +70°C. Propagation delays from input A to output Y range from 2ns to 14ns depending on transition direction.

Feature Summary

• Advanced oxide-isolated ion-implanted Schottky TTL process for high-speed performance
• Data flow-thru pinout arrangement with inputs and outputs on opposite sides of the package
• 3-STATE control gate using a 2-input NOR configuration for high impedance states
• P-N-P inputs designed to reduce DC loading

Applications

• High-speed data bus buffering applications
• Memory address drivers
• Clock drivers
• Bus-oriented transmissions

Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels. Confirm the specific ordering code matches the required package type, as the DM74ALS541 series is available in multiple packages including SOIC and SOP. Ensure that any suffixes appended to the base part number are explicitly supported by the manufacturer's documentation before procurement.

Selection Notes

Select this component when a bidirectional octal buffer with 3-STATE capability is required. The data flow-thru architecture is specifically advantageous for printed circuit board layout optimization compared to standard parallel I/O configurations. Verify that the system logic levels align with the specified VIH and VIL thresholds for reliable operation within the ALS family standards.

Part Context

This component belongs to the 74ALS logic family, characterized by advanced Schottky technology offering higher speed than standard TTL while maintaining lower power consumption. The DM74ALS541 variant specifically provides eight non-inverting buffers with tri-state outputs, serving as a critical interface element in digital systems requiring signal isolation and drive strength enhancement.

Replacement Considerations

Direct substitutes include the SN74ALS541DW and SN74ALS541NSR from Texas Instruments.
