Flip Flops datasheet and documents for SN74ALS874BDWR
Flip Flops Overview
The SN74ALS874BDWR is a dual 4-bit D-type edge-triggered flip-flop manufactured by Texas Instruments in the ALS logic series. It features a 24-pin SOIC package and operates within a supply voltage range of 4.5V to 5.5V. The device includes a clear function and supports TTL input levels. Key electrical characteristics include a maximum propagation delay of 14ns, a low-level output current of 24mA, and a high-level output current of -2.6mA. It functions as a bus driver with non-inverting polarity and has a load capacitance of 50pF.
Flip Flops Feature Summary
- Dual 4-bit D-type edge-triggered flip-flop architecture
- Integrated clear functionality for synchronous reset
- TTL-compatible input levels with non-inverting output
- High-speed operation with low propagation delay
Flip Flops Applications
- Data storage and buffering in digital systems
- Shift register implementations
- Bus interface circuits requiring edge-triggered latching
- General-purpose logic applications in industrial control
Flip Flops Procurement Notes
Verify the specific ordering suffix BDWR against official Texas Instruments documentation to confirm the SOIC-24 surface-mount package and reel packaging configuration. Ensure compatibility with standard 3.3V or 5V logic interfaces by checking input threshold specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration into assembly processes.
Flip Flops Selection Notes
Select this component when a dual 4-bit edge-triggered storage element with active clear is required. The ALS series offers faster switching speeds compared to standard 74LS devices while maintaining lower power consumption than 74S variants. Consider the 24-pin SOIC footprint for PCB layout constraints and verify that the 24mA sink capability meets the load drive requirements of the destination circuitry.
Flip Flops Part Context
This part belongs to the SN74ALS family of advanced low-power Schottky logic devices produced by Texas Instruments. The ALS series was designed to provide improved speed-to-power ratios relative to earlier generations. The SN74ALS874 specifically addresses applications needing multiple independent D-type flip-flops with clear inputs in a compact integrated circuit form factor.
