The ALVT family is a speed upgrade of the LVT family. It combines low power dissipation and low noise of CMOS with the high speed and high output drive of bipolar products. NXP’s ALVT devices exhibit highly stable static and dynamic characteristics over a wide temperature range.
Features and benefits
- 1.5 ns typical propagation delay
- Output drive capability IOH / IOL = -32 / +64 mA

- Power-up / power-down 3-state
- Live insertion
- Bus hold on data inputs
- Optional: Buffers and drivers with 30 Ω integrated termination resistor
- Backplane drivers
- Telecom and networking equipment

ALVT logic devices are specified over 2.7 V to 3.6 V 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.
NXP’s ALVT products are fully specified from -40 °C to 85 °C.
