Product Overview: 74LVT2244DB from NXP
The 74LVT2244DB is a high-performance, low-voltage BiCMOS device integrated within NXP's renowned LVT series. This product is designed for use in 3.3V systems, offering a robust interface between 3.3V and 5V buses in a bidirectional manner. The 74LVT2244DB is characterized by its high-speed performance while maintaining low power consumption, making it an ideal choice for interfacing with high-speed microprocessors or memory units within your electronic designs.
This octal buffer and line driver features eight high-speed non-inverting buffers/line drivers with 3-state outputs. The 3-state outputs are essential for multiplexed data transmission and can be put in a high-impedance state, effectively disconnecting the output from the rest of the circuit, which is particularly useful in bus-oriented systems.
Key specifications of the 74LVT2244DB include:
- Wide operating voltage range of 2.7V to 3.6V, with 5V tolerant inputs and outputs for interfacing with 5V logic levels without damage.
- High-speed performance equivalent to that of 5V ABT devices, with a maximum propagation delay of 3.8ns.
- Low power consumption, with a typical I_CC of only 40µA, reducing the overall power requirements of the system.
- Live insertion and extraction permitted, thanks to the bus hold feature on the data inputs, which eliminates the need for external pull-up or pull-down resistors.
- Power-up 3-state feature allows for better power management and system initialization.
- ESD protection exceeds JESD 22, ensuring durability and longevity in harsh electrical environments.
- Latch-up performance exceeds 500mA, providing additional protection against over-current conditions.
The package for the 74LVT2244DB is a SSOP (Shrink Small Outline Package) with 20 pins, providing a compact footprint while still allowing for ease of integration into PCB designs. Its compact size and power efficiency make it a suitable choice for a wide array of applications, including telecommunications, computing, and industrial systems where space and power are at a premium.
With its combination of speed, power efficiency, and robust protection features, the 74LVT2244DB from NXP is a reliable and versatile solution for your high-speed logic conversion and buffering needs.
