Latches

SN74ALS873BDW Description

The SN74ALS873BDW from Texas Instruments is a high-performance dual 4-bit transparent latch with tri-state outputs, designed for surface-mount applications in the 74ALS series. Packaged in a 24-SOIC tube, it operates within a 4.5V to 5.5V supply range and features a propagation delay of just 8ns, ensuring rapid data handling. With two independent 4:4 circuits, this latch supports bidirectional data flow and offers tri-state outputs for bus-oriented systems. It is ROHS3 compliant and REACH unaffected, making it suitable for environmentally conscious designs.

SN74ALS873BDW Features

• Dual 4-bit transparent latch with independent control for flexible data management.
• Tri-state outputs enable bus sharing and reduce system congestion.
• High-speed operation: 8ns propagation delay for efficient data transfer.
• Wide voltage range (4.5V–5.5V), compatible with standard TTL logic levels.
• Robust output drive: 2.6mA (high) / 24mA (low) current capability for interfacing with multiple loads.
• Surface-mount 24-SOIC package for compact PCB designs.
• Industrial reliability: MSL 1 (unlimited) moisture sensitivity and 0°C to 70°C operating temperature range.

SN74ALS873BDW Applications

• Data buffering and storage in microprocessor/microcontroller systems.
