SN74ACT16373QDLREP

Overview

The SN74ACT16373QDLREP is a 16-bit transparent D-type latch featuring three-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and utilizes the 74ACT logic series. The device is housed in a 48-pin SSOP package with surface-mount installation. Key electrical parameters include a propagation delay of 9.7 ns at 4.5 V to 5.5 V, static current of 8 uA, low-level output current of 32 mA, and high-level output current of -24 mA. It supports non-inverting polarity and functions across an operating temperature range from -40 °C to +85 °C.

Feature Summary

• Provides sixteen independent transparent D-type latches for data storage applications
• Features three-state outputs to facilitate bus-driven architectures
• Operates reliably within standard 5 V logic supply voltage ranges

Applications

• Parallel-to-serial data conversion circuits
• Bus-oriented memory mapping systems
• High-speed digital signal processing interfaces

Procurement Notes

Verify the Q suffix indicates automotive qualification requirements against specific project standards. Confirm the DLREP suffix corresponds to the correct 48-SSOP tape and reel packaging configuration. Ensure compatibility with existing board layouts regarding pin assignments and thermal dissipation characteristics before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring 16-bit parallel data latching with tri-state control capabilities. It is suitable for applications demanding fast switching speeds under standard 5 V operation. Consider alternative LVC or AVC series devices if lower voltage operation below 4.5 V is required for power efficiency.

Part Context

This part belongs to the SN74ACT16373 family of 16-bit latches. It shares functional similarities with other ACT series components but is distinguished by its specific automotive-grade qualification indicated by the Q prefix. The device serves as a critical interface element in complex digital systems requiring robust data retention and high-speed transfer rates.

Replacement Considerations

SN74ACT16373DLR is a verified commercial-grade substitute offering identical electrical performance without automotive qualification.
