74ACT16373DL

Latches Overview

The SN74ACT16373DL is a 16-bit transparent D-type latch manufactured by Texas Instruments. It features two independent circuits, each handling eight bits, housed in a 48-pin SSOP package. The device operates with non-inverting outputs and supports CMOS and TTL input types. Key electrical parameters include a propagation delay of 9.7 ns at supply voltages between 4.5 V and 5.5 V. Output drive capabilities are specified as -24 mA for high-level and 32 mA for low-level currents. Static current consumption is typically 8 uA. The component functions within an operating temperature range from -40°C to +85°C.

Latches Feature Summary

• Provides 16-bit data storage via two independent 8-bit transparent latches
• Features three-state outputs for bus-oriented memory applications
• Supports direct interface with standard logic families including CMOS and TTL inputs

Latches Applications

• Bus-oriented memory register implementations
• I/O port buffering and latching
• Parallel-to-serial conversion circuits

Latches Procurement Notes

Verify the specific suffix against the datasheet to confirm package type and tape-and-reel specifications. Ensure the voltage rating matches the system requirements of 4.5 V to 5.5 V. Confirm RoHS compliance status if environmental regulations apply to the assembly process. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before procurement.

Latches Selection Notes

Select this component when a 16-bit parallel latch with tri-state capability is required for 5 V logic systems. The ACT series offers faster switching speeds compared to standard 74LS equivalents. Consider the 48-SSOP package dimensions for PCB layout constraints. Verify that the input voltage levels remain compatible with the driving logic family to ensure reliable signal integrity across the full operating temperature range.

Latches Part Context

This device belongs to the Texas Instruments 74ACT logic family, designed for high-speed digital applications. It serves as a parallel data storage element within larger digital systems. The 16373 designation indicates a 16-bit configuration with transparent latch functionality. It is commonly used in microprocessor-based systems for holding address or data lines during bus cycles.

Latches Replacement Considerations

The SN74ACT16373DLRG4 is a verified lead-free replacement variant with identical electrical characteristics. Other 74ACT16373 derivatives may offer different packaging options but maintain functional compatibility.
