74ACT16374DL

Overview

The SN74ACT16374DL is an octal D-type flip-flop with three-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and features a propagation delay of 8.8 ns at 5 V with 50 pF load. The device provides symmetric output drive currents of 24 mA for both high and low states, with a static current of 8 µA. It utilizes a 48-SSOP package and supports a clock frequency of 65 MHz across the industrial temperature range of -40°C to +85°C.

Feature Summary

• Octal D-type edge-triggered flip-flops with non-inverting logic
• Three-state outputs for bus-oriented memory operations
• TTL-compatible inputs supporting standard digital signaling

Applications

• Bus-oriented memory register implementations
• I/O buffer configurations for data isolation
• Parallel-to-serial data conversion circuits

Procurement Notes

Verify the specific suffix 'DL' corresponds to the SSOP-48 tube packaging variant rather than the tape-and-reel 'DLR' version. Confirm RoHS compliance status and check for any recent Product Change Notifications regarding assembly materials or pin compatibility. Ensure the supplier source matches the original manufacturer specifications for the ACT series logic family.

Selection Notes

Select this component when designing systems requiring 8-bit parallel storage with tri-state control in a 5V environment. The 48-SSOP package suits applications needing compact surface-mount layouts. Consider the 8.8 ns delay and 24 mA drive capability for timing-critical bus interfaces where TTL input thresholds are required for reliable signal reception.

Part Context

This part belongs to the SN54/74ACT16374 family of octal flip-flops. It shares functional similarities with the SN74LVTH16374 but differs in operating voltage and speed characteristics. The ACT series offers faster switching speeds compared to standard HC or HCT families while maintaining CMOS power efficiency suitable for general-purpose logic applications.

Replacement Considerations

Public confirmed substitute part numbers include SN74ACT16374DLR for tape-and-reel packaging variants.
