DM74LS374N

Overview

The DM74LS374N is an octal D-type edge-triggered flip-flop manufactured by onsemi. It features eight positive-edge triggered D-type flip-flops with three-state outputs in a 20-pin PDIP package. The device operates within a supply voltage range of 4.5V to 5.5V and supports a maximum clock frequency of 35 MHz. Propagation delay is specified at 16ns @ 5V, 50pF. Output drive capabilities include 2.6mA high-level and 24mA low-level current. Static current (Iq) is 19 mA. Operating temperature ranges from 0°C to 70°C.

Feature Summary

Octal configuration with eight independent D-type flip-flops
Three-state outputs designed for direct bus line driving
Positive-edge triggering mechanism for data capture

Applications

Buffer registers implementation
I/O port interfacing
Bidirectional bus drivers
Working registers in digital systems

Procurement Notes

Verify component status as the DM74LS374N is listed as obsolete and no longer manufactured. Confirm availability through authorized distributors or secondary markets. Ensure replacement components meet identical electrical specifications and pinout compatibility. Validate datasheet revisions and manufacturer documentation for accurate technical parameters before integration into new designs.

Selection Notes

Select this component for legacy TTL logic applications requiring octal storage with bus-compatible outputs. Consider alternative active parts if long-term supply stability is required. Evaluate propagation delay and output drive strength against system timing requirements. Verify package dimensions and thermal characteristics for PCB layout compatibility.

Part Context

Part of the 74LS series family, providing standard logic functionality with low power consumption relative to earlier TTL families. Designed for general-purpose digital storage and transfer applications. Compatible with standard 5V logic systems. Part number indicates onsemi manufacturing origin and LS logic type designation.
