Collection: Digital Latch ICs - Transparent & Gated Logic Memory

High-Speed Digital Latches for Real-Time Logic State Storage & Control

Our Digital Latch ICs provide transparent, level-sensitive memory elements for real-time data capture and logic state control in digital systems. Unlike edge-triggered flip-flops, latches continuously update outputs while enabled, making them ideal for timing-critical applications requiring immediate data reflection across industrial, automotive, and embedded system designs.

Key Features & Technologies:

• Transparent Operation: Level-sensitive enable inputs allow real-time data pass-through for dynamic logic state updates
• Multiple Latch Types: D-type latches, SR latches, and gated latches for diverse memory and control applications
• High-Speed Performance: Nanosecond propagation delays for fast data capture and state transitions
• 3-State Outputs: Tri-state output configurations for bus-oriented architectures and multi-device systems
• Wide Voltage Range: Support for 1.8V to 5V logic levels and mixed-voltage interfacing
• Low Power CMOS: Energy-efficient designs with minimal static and dynamic power consumption

Latches vs. Flip-Flops:

Latches differ from flip-flops in their timing behavior: latches are transparent (level-sensitive) and update outputs continuously while the enable signal is active, whereas flip-flops are edge-triggered and capture data only on clock transitions. This makes latches ideal for asynchronous control, address decoding, and applications requiring immediate data reflection without waiting for clock edges.

Primary Applications:

Our latch portfolio supports address latches in microprocessor systems, data bus buffers, temporary storage registers, asynchronous control circuits, state machines, I/O port expansion, and timing-critical logic in embedded controllers and digital signal processing systems.
