Frequently Asked Questions
How wide is the data path on the SN74LVC16373AZQLR?
The SN74LVC16373AZQLR is a 16-bit device, capable of simultaneously latching and driving 16 parallel data lines in a single package, making it ideal for full 16-bit bus interfacing in microprocessor memory systems and FPGA peripheral designs.
What supply voltage range does the SN74LVC16373AZQLR support?
The SN74LVC16373AZQLR operates from 1.65V to 3.6V supply voltage as part of the LVC low-voltage CMOS family, while its inputs are 5V tolerant, allowing it to interface between 5V legacy systems and modern 3.3V or 1.8V logic without level-shifting components.
What is the output drive capability of the SN74LVC16373AZQLR?
The SN74LVC16373AZQLR provides a maximum output low sink current (IOL) of 24 mA, which is sufficient to drive heavily loaded bus lines and backplane traces while maintaining signal integrity at full 16-bit bus width in high-capacitance PCB environments.
What package is the SN74LVC16373AZQLR available in?
The SN74LVC16373AZQLR is available in a 56-ball PBGA (Plastic Ball Grid Array) package with tape and reel packaging, which provides a very small PCB footprint for high-density board designs in portable and communication equipment where space is at a premium.
What is a transparent latch and how does it work in the SN74LVC16373AZQLR?
A transparent latch passes input data directly to the output while the enable signal is active (latch transparent), and holds the last input state when the enable is deasserted (latch opaque). In the SN74LVC16373AZQLR, the active-low enable allows data to flow through all 16 bits simultaneously during bus write cycles and holds the captured data stable on the outputs afterward.
