Overview
The IDT74ALVC16820APF is a 3.3V CMOS octal D-type flip-flop with 3-state outputs, manufactured using 0.5-micron technology. It features independent clock inputs for each pair of flip-flops and an asynchronous clear input. The device operates within a supply voltage range of 2.7V to 3.6V and supports industrial temperature ranges. It is housed in a 56-pin TVSOP package.
Feature Summary
- Octal configuration with independent clocking for enhanced timing control
- Asynchronous clear function for immediate output reset
- 3-state outputs to facilitate bus-oriented memory and register designs
Applications
- Bus-oriented memory register implementations
- I/O port connections for data buffering
- Clock buffer applications requiring high fan-out
Procurement Notes
Verify the specific suffix 'PF' corresponds to the TVSOP-56 package and tube packaging format. Confirm RoHS compliance status and lead times directly with Renesas or authorized distributors, as IDT logic products are now managed under the Renesas portfolio. Ensure the component meets current environmental regulations for your region.
Selection Notes
Select this component when designing systems requiring octal storage with independent clock domains per pair. Compare against the 74ALVC16821 if registered inputs are needed instead of direct D-inputs. Consider the TVSOP-56 package constraints for PCB layout and thermal management compared to SSOP alternatives.
Part Context
This part belongs to the ALVC (Advanced Low-Voltage CMOS) family, offering high-speed performance at 3.3V. It complements other bus transceivers like the 74ALVC162245 by providing storage functionality rather than just direction control. The device is widely used in high-density digital systems requiring reliable data latching.
Replacement Considerations
Cross-reference with Texas Instruments SN74ALVC16820PWR or Nexperia 74ALVC16820DL for pin-compatible alternatives. Verify electrical characteristics and package dimensions match before substitution.
