SN74HCT374DWR in a 20-pin SOIC (300 mil) package. An octal D-type latch with 3-state outputs that captures data on the clock edge and holds it on the Q outputs until the next clock, with an output enable control for bus sharing. Key benefits - Reliable data storage and timing - Eight D-type latches provide a convenient data storage stage to stabilize signals for downstream devices. - Edge-triggered capture helps synchronize data transfer in digital circuits. - Flexible bus architecture - 3-state outputs enable easy sharing of a common data bus among multiple devices. - Output enable allows selective drive or high-impedance when not in use. - Compatibility and ease of integration - TTL-compatible HCT inputs enable reliable interfacing with standard logic levels in 5V systems. - Suitable for a variety of designs that require fast, predictable latching with minimal component count. - Compact and practical packaging - SOIC 20-pin, 300 mil wide package supports compact, surface-mount layouts and straightforward manufacturing. What makes it suitable - Function: octal D-type latch with 3-state outputs for data storage and bus buffering - Compatibility: TTL-compatible input thresholds for reliable interfacing with common logic families - Size: compact 20-pin SOIC package with 300 mil width for dense PCB layouts - Performance: enables fast, edge-driven data capture with controlled output behavior Use scenarios - Data bus buffering: latch data from a processor or microcontroller onto a shared bus, then enable outputs as needed to devices on the bus. - Parallel-to-serial or register stage: capture parallel data from a peripheral and hold it for downstream processing or transfer to another device. - I/O expansion and interfacing: act as a temporary storage/register when connecting multiple sensors or peripherals to a microcontroller, ensuring stable input data during timing-sensitive operations.
