Flip Flops datasheet and documents for SN74ABT16821DLR
Flip Flops Overview
The SN74ABT16821DLR is a Texas Instruments bus interface flip-flop from the ABT logic series. It features two circuits with non-inverting TTL inputs and 3-state outputs in an SSOP-56 package. Operating on a 4.5 V to 5.5 V supply, it delivers high drive capability with -32 mA high-level and 64 mA low-level output currents. The device exhibits a propagation delay of 5.5 ns and supports surface-mount installation.
Flip Flops Feature Summary
- Integrates D-type flip-flops for registered data storage within a bus interface architecture
- Provides high-drive 3-state outputs capable of driving buses directly
- Accepts standard TTL input voltage levels for broad compatibility
Flip Flops Applications
- High-speed parallel data acquisition systems
- Registered bus transceivers for memory interfaces
- Data buffering in industrial control networks
Flip Flops Procurement Notes
Verify the specific suffix 'DLR' corresponds to the SSOP-56 tape-and-reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation. Ensure the operating temperature range aligns with system requirements before finalizing procurement orders.
Flip Flops Selection Notes
Select this component when registered bus interfacing with high current drive is required. The ABT technology offers speed comparable to ALVC with CMOS-compatible inputs. Verify that the 5.5 V maximum supply voltage matches the target system power rails.
Flip Flops Part Context
This part belongs to the SN74ABT family of BiCMOS logic devices. It provides registered functionality distinct from unregistered buffers or latches. The SSOP-56 package allows for compact surface-mount designs in dense circuit boards.
Flip Flops FAQ
Is the SN74ABT16821DLR a latch or a flip-flop?
It is a D-type flip-flop, providing edge-triggered data storage rather than level-sensitive latching.
What is the input logic level requirement?
The device accepts TTL input levels, ensuring compatibility with standard digital logic families.
