74ACT16373DLRG4

Latches Overview

The SN74ACT16373DLRG4 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-lead SSOP package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports non-inverting outputs with three-state capability. It exhibits a propagation delay of 9.7 ns at 4.5 V to 5.5 V and maintains a static current of 8 uA. The component provides a low-level output current of 32 mA and a high-level output current of -24 mA, functioning reliably across an operating temperature range from -40 C to +85 C.

Latches Feature Summary

• Transparent data storage architecture allowing direct input-to-output transmission when enabled
• Three-state outputs for effective bus line driving and system isolation
• Non-inverting logic polarity ensuring signal integrity preservation

Latches Applications

• Parallel data buffering in digital communication systems
• Address latching for memory interface control
• I/O port expansion in microcontroller-based designs

Latches Procurement Notes

Verify the complete part number including the G4 suffix to confirm RoHS compliance and lead-free status. Ensure the SSOP-48 package variant matches your PCB footprint requirements. Confirm that the 4.5 V to 5.5 V supply voltage aligns with your system design specifications before procurement.

Latches Selection Notes

Select this component when a 16-bit transparent latch with three-state outputs is required for 5 V logic applications. The ACT series offers faster switching speeds compared to standard LS logic. Verify that the 48-SSOP package fits your assembly constraints and that the 32 mA sink current meets your load requirements.

Latches Part Context

This device belongs to the 74ACT logic family, designed for high-speed CMOS operations compatible with TTL inputs. The 74ACT16373 variant specifically provides 16-bit latching functionality. It serves as a critical interface component for managing parallel data streams in complex digital circuits requiring precise timing control.

Latches Replacement Considerations

The SN74ACT16373DLR is the non-RoHS compliant equivalent. The SN74ACT16373ADGGRG4 offers a TSSOP-48 package alternative. Cross-reference pinouts and electrical characteristics carefully when substituting.
