Frequently Asked Questions
What voltage range and how many channels does the SN74ALVTH16244DGG support?
The SN74ALVTH16244DGG operates on a 2.3 V to 3.6 V supply voltage and provides 16 buffering channels with 3-state outputs. It features TTL-compatible CMOS inputs, making it suitable for interfacing between different logic voltage levels in modern digital systems without additional level-shifting components.
What is bus-hold and why is it important in the SN74ALVTH16244DGG?
Bus-hold is an integrated circuit feature that holds the last driven logic state on a bus line when the driving source is removed or tri-stated. In the SN74ALVTH16244DGG, bus-hold eliminates the need for external pull-up or pull-down resistors, preventing floating inputs, reducing power consumption from indeterminate bus states, and simplifying PCB layout.
What are the 3-state outputs used for in the SN74ALVTH16244DGG?
The 3-state outputs in the SN74ALVTH16244DGG allow the device to effectively disconnect from the bus by entering a high-impedance state. This enables multiple buffers to share the same data bus without conflict, which is essential in bus-oriented architectures such as microprocessor address/data buses, memory interfaces, and FPGA I/O expansion applications.
What are typical applications for the SN74ALVTH16244DGG?
Typical applications include address and data bus buffering in microprocessor and DSP systems, memory expansion interfaces, FPGA I/O buffering, backplane bus drivers, and level-shifting between 2.5 V and 3.3 V logic domains. The 16-channel width and integrated bus-hold make it particularly efficient for high-density board designs requiring simultaneous buffering of wide parallel buses.
