TC74HC373APF

Overview

The TC74HC373APF is a D-type transparent latch manufactured by Toshiba Semiconductor and Storage. It features eight independent circuits within a single package, providing an 8:8 data path configuration. The device utilizes a standard 20-DIP (Dual In-line Package) with a pin count of twenty for through-hole mounting. It operates on a supply voltage range of 2V to 6V. The logic type is defined as a D-type transparent latch with tri-state outputs. The component supports an operating temperature range from -40°C to 85°C.

Feature Summary

• Transparent latching functionality allows direct data passage when enabled.
• Tri-state output capability enables bus line sharing and isolation.
• Eight-bit parallel data handling via a single integrated circuit.

Applications

• Parallel-to-serial data conversion interfaces
• Memory address buffering in digital systems
• General-purpose register storage

Procurement Notes

Verify the specific suffix 'PF' against the manufacturer's current datasheet to confirm the package variant and lead-free status. Ensure the procurement channel sources directly from authorized distributors or the manufacturer to avoid counterfeit components. Confirm that the 20-DIP form factor matches the target PCB footprint requirements before finalizing orders.

Selection Notes

Select this component when a through-hole DIP package is required for prototyping or legacy board designs. The HC series offers compatibility with standard CMOS logic families. Consider the propagation delay specifications if high-speed timing constraints exist. Verify that the 2V to 6V supply range aligns with the system power architecture.

Part Context

This part belongs to the 74HC logic family, which provides high-speed CMOS performance comparable to TTL while maintaining low power consumption. The 74HC373 designation indicates an octal transparent latch with three-state outputs. Toshiba manufactures this component under the TC prefix, denoting their commercial-grade industrial logic products.

Replacement Considerations

Cross-reference with other manufacturers offering the 74HC373 specification in a 20-DIP package. Verify pinout compatibility and electrical characteristics such as output drive current and propagation delay before substituting.
