Frequently Asked Questions
What is the operating voltage range of the SN74LVC16244ADGGR?
The SN74LVC16244ADGGR operates over a voltage range of 1.65V to 3.6V, making it suitable for modern low-voltage logic systems. This wide range allows it to interface with 1.8V, 2.5V, and 3.3V supply rails commonly found in FPGAs, microcontrollers, and DSPs.
How does the enable control work on the SN74LVC16244ADGGR?
The SN74LVC16244ADGGR uses active-low output enable (OE) pins to control the 3-state outputs. When OE is driven low, the outputs are enabled and data flows from inputs to outputs. When OE is driven high, the outputs enter a high-impedance (3-state) condition, effectively disconnecting the driver from the bus. The device has two OE pins, each controlling 8 bits of the 16-bit bus.
What package does the SN74LVC16244ADGGR use and what are its dimensions?
The SN74LVC16244ADGGR comes in a 48-pin TSSOP package (JESD-30 code R-PDSO-G48), which is a compact surface-mount small outline package. The TSSOP format offers a reduced footprint compared to standard SOP packages, making it well-suited for space-constrained PCB designs in portable and high-density electronics.
What are common applications for the SN74LVC16244ADGGR?
This device is commonly used as a bus buffer or line driver in microprocessor and FPGA systems where 16-bit data or address buses need to be driven with sufficient current. Typical applications include memory bus expansion, backplane signal driving, I/O port isolation, and level translation between 1.8V and 3.3V logic domains in industrial and communications equipment.
Is the SN74LVC16244ADGGR RoHS compliant?
Yes, the SN74LVC16244ADGGR is fully RoHS compliant. It carries Pb-free (lead-free) status (Pbfree Code: Yes) and meets the JESD-609 e4 specification, confirming it is manufactured without restricted hazardous substances. It also carries a YTEOL rating of 15 years, reflecting long-term availability and environmental reliability.
