74ACT16374DLR

Overview

The Texas Instruments 74ACT16374DLR is a dual, 8-bit D-type flip-flop integrated circuit designed for high-speed digital logic applications. It operates within a supply voltage range of 4.5V to 5.5V and features positive-edge triggering with tri-state, non-inverting outputs. The device supports a maximum clock frequency of 65 MHz and delivers output drive currents of 24mA for both high and low states. Maximum propagation delay is specified at 8.8ns under 5V supply with 50pF load conditions. Static current consumption is limited to 8µA. The component is housed in a 48-BSSOP package measuring 7.50mm in width and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Dual independent 8-bit D-type flip-flops with positive-edge clock triggering
• Tri-state outputs providing high-impedance isolation when disabled
• High-speed operation supporting clock frequencies up to 65 MHz
• Robust output drive capability with 24mA sourcing and sinking capacity

Applications

• Parallel-to-serial data conversion circuits
• Buffering and register storage in high-speed digital systems
• Clock domain crossing synchronization stages
• Data acquisition system input latching

Procurement Notes

Verify the specific ordering suffix to confirm the tape-and-reel packaging configuration required for automated assembly processes. Confirm RoHS3 compliance status and ensure the lead-free finish meets environmental regulations for the target market. Validate that the 48-BSSOP footprint matches the designated PCB land pattern dimensions to prevent soldering defects during surface-mount placement.

Selection Notes

Select this component when designing 5V logic interfaces requiring high-speed data capture with minimal propagation delay. Ensure the application voltage remains strictly within the 4.5V to 5.5V operational window to maintain timing specifications. Consider the 48-pin package density for board space constraints and verify that the 24mA output drive is sufficient for the connected load capacitance without signal integrity degradation.

Part Context

This device belongs to the Texas Instruments 74ACT series, which utilizes advanced CMOS technology to achieve performance levels comparable to standard TTL logic while offering lower power consumption. The 74ACT16374 provides a cost-effective solution for replacing older bipolar logic families in modern designs. It serves as a foundational building block for complex sequential logic circuits requiring reliable data storage and transfer capabilities in industrial and consumer electronics.

Replacement Considerations

The 74ACT16374DL is a discontinued variant; the 74ACT16374DLR serves as the active equivalent with identical electrical characteristics but differs in reel-based packaging.
