The CD74LPT16240ASM from Harris Corporation is a 16-bit inverting buffer designed for 3.3V systems. It contains four 4-bit channels with 3-State outputs, providing inverted buffering for bus-oriented applications. Operating from 2.7V to 3.6V, it is compatible with standard 3.3V logic. Each output can sink or source 24mA, offering strong drive capability for demanding loads. The device is available in a 48-BSSOP package, suitable for high-density PCB designs. Typical applications include memory buffering, signal inversion, and bus isolation in computing and industrial equipment.
- 3.3V Operation: Matches common low-voltage logic standards.
- High 24mA Output Drive: Ensures reliable signal transmission over longer traces.
- 4 Channels of 4 Bits: Provides flexible routing options for complex buses.
- 3-State Outputs: Enables bus sharing and prevents data corruption.
- Industrial Temperature Range: Operates from -40°C to 85°C.
