DM74ALS374WMX

Overview

The DM74ALS374WMX is an octal D-type edge-triggered flip-flop manufactured by Fairchild Semiconductor. It features totem-pole 3-STATE outputs designed for driving highly-capacitive or low-impedance loads. The device operates within a supply voltage range of 4.5V to 5.5V and supports a maximum clock frequency of 35 MHz. Key electrical parameters include a maximum propagation delay of 16ns at 5V with 50pF load, static current consumption of 19 mA, and output currents of 2.6mA (high) and 24mA (low). It is housed in a 20-PDIP package.

Feature Summary

• Octal D-type edge-triggered flip-flop configuration
• Totem-pole 3-STATE outputs for bus-driven systems
• Advanced Low Power Schottky (ALS) technology

Applications

• Memory systems
• Microprocessor systems
• Asynchronous bidirectional data buses
• Buffer registers
• I/O ports

Procurement Notes

Verify component authenticity through authorized distributors. Confirm datasheet version compatibility with design requirements. Check for RoHS compliance status if environmental regulations apply. Ensure proper handling procedures are followed due to the component's age and discontinuation status. Validate pinout alignment with existing PCB layouts before integration.

Selection Notes

Select this component for applications requiring high-speed logic with moderate power consumption. The ALS series offers faster switching than standard TTL while consuming less power than LS variants. Consider the 3-STATE output capability for direct bus interfacing without additional interface components. Evaluate thermal management needs given the 19 mA static current draw.
