Frequently Asked Questions
How many bits does 74ALVTH162245GRG4 support and in which direction can data flow?
74ALVTH162245GRG4 is a 16-bit bus transceiver that supports bidirectional data flow under common control. Both A-to-B and B-to-A transfer directions are selectable, making it ideal for processor data buses, memory interfaces, and backplane interconnects where the bus direction must be switched dynamically between read and write cycles.
What supply voltage does 74ALVTH162245GRG4 operate from, and how does it fit into 3.3 V digital systems?
74ALVTH162245GRG4 operates at a 3.3 V supply and is part of the ALVT logic family designed for high-speed low-voltage operation. It is fully compatible with LVTTL signal levels, allowing direct connection to 3.3 V microprocessors, FPGAs, and DSPs without external level-shifting components, simplifying system design and reducing BOM cost.
What is the load capacitance specification of 74ALVTH162245GRG4 and why does it matter for signal integrity?
74ALVTH162245GRG4 is characterized at a load capacitance of 30 pF, which represents typical PCB trace plus receiver input capacitance. Operating within this specified load ensures the propagation delay and output drive strength remain within the ALVT family timing budget, preventing setup-time violations in high-speed 3.3 V parallel bus designs running at clock frequencies above 50 MHz.
Which package does 74ALVTH162245GRG4 use, and how does it compare to wider DIP packages for board density?
74ALVTH162245GRG4 is housed in a 48-pin TSSOP package with a 0.5 mm pin pitch, providing a dramatically smaller PCB footprint than a 48-pin DIP package. The TSSOP outline reduces the occupied board area by more than 60% compared to through-hole equivalents, enabling high channel density in multilayer PCBs used in networking, storage controllers, and embedded processor boards.
