ALVT logic devices are specified over 2.7V to 3.6V and support live insertion. With output drive as high as 64 mA and typical propagation delay of 1.5 ns, the ALVT family consists of 16-bit parallel interface logic.
Power up reset, power up 3-state output, bus hold and live insertion are some of the advanced features of these devices making them ideal for parallel backplane applications.
ALVT products are available in standard SSOP and TSSOP packages.
Nexperia's ALVT products are fully specified from -40°C to 85°C.
