The CD74LPT16244ASM is a quad-channel non-inverting buffer from Harris Corporation, part of the 74LPT logic family. Designed for low-voltage 3.3V systems, it operates from 2.7V to 3.6V and features 3-State outputs for bus sharing. With balanced output currents of 24mA source and 24mA sink, it provides reliable signal buffering for a variety of loads. This buffer is ideal for memory interfaces, portable devices, and industrial sensor applications. The 48-BSSOP package offers a compact footprint for space-constrained designs.
- Quad-Channel Design: Provides four independent buffers in a single package, saving board space.
- Low-Voltage Operation (2.7V-3.6V): Reduces power consumption in battery-powered devices.
- Balanced 24mA Drive: Ensures symmetrical signal rise and fall times for improved signal integrity.
- 3-State Outputs: Allows for efficient bus sharing and prevents data contention.
