Overview
The SN74ACT16821DL is an 18-bit bus interface flip-flop manufactured by Texas Instruments. It features a single circuit with non-inverting polarity and TTL-compatible inputs. The device provides 3-state outputs capable of sourcing -24 mA and sinking 24 mA. It operates within a supply voltage range of 4.5 V to 5.5 V. The component exhibits a propagation delay of 11.5 ns. It is housed in a 56-pin SSOP package designed for surface mount installation.
Feature Summary
- Provides 18-bit data storage via D-type flip-flops with bus interface architecture
- Features high-drive 3-state outputs for efficient signal transmission
- Ensures compatibility with standard TTL input logic levels
Applications
- High-speed parallel data buffering systems
- Bus interface circuits requiring wide data word processing
- Digital signal routing and temporary data storage applications
Procurement Notes
Verify the specific suffix 'DL' corresponds to the SSOP-56 plastic package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation, as legacy variants may differ. Ensure the design supports the required 4.5V to 5.5V operating range and validates the 11.5ns timing constraints against system requirements before finalizing procurement.
Selection Notes
Select this component for designs requiring 18-bit synchronous data latching with direct bus interfacing capabilities. The ACT series offers speed-performance comparable to LS-TTL while maintaining CMOS low power consumption. Consider the 56-pin SSOP footprint for layout constraints. Verify that the 3-state output drive strength meets the load requirements of the destination bus lines without additional buffering.
Part Context
This part belongs to the Texas Instruments 74ACT family of advanced CMOS logic devices. The 74ACT1682x series specifically addresses applications needing wide-word data storage. It serves as a bridge between high-speed processors and peripheral buses. The device integrates clocked storage elements optimized for system-level data integrity and timing control in complex digital architectures.
Replacement Considerations
Check for SN74ACT16821DR (tape and reel version) if automated assembly is required. Verify cross-brand equivalents from manufacturers like ON Semiconductor or NXP, ensuring pinout and electrical specifications match exactly.
