Frequently Asked Questions
What is the SN74ALVCH16821DGGR and what does it do?
The SN74ALVCH16821DGGR is a 20-bit bus-interface D-type flip-flop (registered buffer) from Texas Instruments in the ALVCH logic family. It captures 20 bits of data on the rising clock edge and presents them at 3-state outputs, enabling clean bus isolation and pipeline staging in 3.3V digital designs.
What are the key electrical specifications of the SN74ALVCH16821DGGR?
Key specs: 3.3V supply voltage, 20-bit data width, 56-pin TSSOP package (0.65mm pitch), operating temperature -40°C to +85°C, LVTTL-compatible inputs, 3-state outputs controlled by active-LOW OE pin, and ALVCH-series propagation delay (typically 2-4 ns).
What package does the SN74ALVCH16821DGGR use and what is the pin count?
The DGGR suffix designates a 56-pin TSSOP (Thin Shrink Small Outline Package) with 0.65mm lead pitch. This compact surface-mount package is suited for high-density PCB layouts in communications and computing equipment.
What are common applications for the SN74ALVCH16821DGGR?
Typical applications include CPU address and data bus buffering, FPGA I/O expansion registers, memory controller data pipelines, and any 3.3V system requiring wide 20-bit registered paths with 3-state bus-sharing capability.
What are good pin-compatible or functional alternatives to the SN74ALVCH16821DGGR?
Functional alternatives include the SN74ALVCH16821DGGRG4 (automotive-grade variant), SN74ALVCH16821DL (SSOP package), and the SN74BCT16821DL from the BCT logic family. For 5V-tolerant designs, consider the SN74ABT16821 in compatible 56-pin packages.
