The SN74HC573AN and SN74HC573N are 8bit Dtype transparent latches with 3state outputs in a 20pin DIP package. This device family provides nine key features that simplify data handling in digital designs: eight data inputs (D0–D7) and eight data outputs (Q0–Q7) with a control mechanism to latch and hold data, plus a tristate output enable for bus sharing. The result is a flexible data buffering solution suitable for reading, storing, and distributing parallel data signals in a compact, throughhole package. Key benefits Enables reliable data capture and bus sharing with tristate outputs, allowing multiple devices to share a common data bus without conflict. Throughhole DIP20 package supports easy handling, assembly, and breadboarding for prototyping and hobbyist projects. Compatible with standard 74HC logic family devices, facilitating straightforward integration with microcontrollers, processors, and other digital ICs. Available in a 5piece lot, convenient for stocking, testing, and bulk projects. Key attributes Function: 8bit Dtype transparent latch with 3state outputs. Package: DIP20 (20pin dualinline package), throughhole for easy mounting. Model variants: SN74HC573AN and SN74HC573N. Input/output: D0–D7 data inputs; Q0–Q7 outputs; control features include latch enable and output enable for precise timing and bus control. Performance: speed CMOS performance consistent with the 74HC logic family; suitable for synchronous and asynchronous data applications within HC voltage ranges. Applications and use cases Microcontroller and microprocessor data capture: latch parallel data for temporary storage before processing or further transfer. Address/data demultiplexing and bus buffering: hold data during memory access cycles and provide a clean, stable data path to other devices. Display drivers, LED matrices, and peripheral interfaces: buffer data streams and gate them onto shared buses or display control lines without loading the driving circuitry. Package and ordering context Includes 5 pieces per lot in DIP20 packaging, suitable for stocking, prototyping, and smallscale production. Ideal for projects requiring a simple, reliable 8bit latch with controllable outputs in a compact throughhole form factor.
